Yes that's my point with the "if"! And in general I largely agree with you.
The parent comment basically argued vinyl is superior because when artists used vinyl the resulting music was creatively better (because of whatever process). Sure, but then you can't selectively ignore the great music that has been made with other recording technologies. I can point to a lot of good music recorded on tape or digital. Unless we are arguing that music back in the vinyl days was broadly better than now? (Different argument then...)
As for artistic choices, I totally agree that vinyl can be a valid choice! Then it's silly to say one thing is "better" than another.
But in terms of raw technology, I say it's just copium to claim vinyl is in any way superior to digital. Digital's recording capabilities are a superset of vinyl's. There is no magic sauce killer feature unique to vinyl.

Old-school DJing! Imagine carefully positioning the laser on a CD...
Adressing your points:
Music may have been a bigger culturual force during the heights of vinyl record sales. Whether that translated to better music or whether it is some form of survivorship bias: I don't know. In fact I doubt it. But there is something to the music that happened when it was new, e.g. Punk music was better when everybody was still trying to figure out what is punk and what isn't, while today it feels like most bands just copy was has been made in the past. You can extrapolate the same idea to many other genres that developed. So was the music better on average? Probably not. Was it more exiting and had more impact on society, fashion, culture? For sure.
As for vinyl: I agree that digital is superior in terms of sound quality. Nearly every vinyl record is pressed from a digital master nowadays after all. Even those who want "vinyl warmth" could have that easily emulated in digital nowadays. Digital is endlessly flexible, you could theoretically envision (and some have done) a vinyl experience that is purely digital under the hood – or you could do whatever netflix is doing.
But in practise vinyl comes with the experience, forces you to do the ritual, to listen to the whole album, is immensly direct (just the waveform pressed into the material) etc. This is a limitation if vinyl is all you have, but in times where you could listen to 10 nameless streams of sounds at once for the whole day that limitation has become a popular feature. I have friends with pressing plants and all of them have more job offers than they could realistically fulfill for years now.
I'd advice against too easily dismissing the value of the ritual a technological dispositif forces onto the people interacting with said technology. Listening to a vinyl record in a time where people rarely ever sit down and just listen to music in a concentrated way is a thing people look for. Those who say it is because vinyl is technically superior are wrong, but the limitations and the listening habits a technology enforces are unseparably a part of the technology itself. And if you are looking for what vinyl gives you, vinyl is the thing that gives it to you best.
I have huge nostalgia for older analog audio and photo formats for many many reasons. I also don't really miss them. Had a lot of fun and memories with vinyl and processing B&W film in a darkroom--also shot a lot of slides--but you can't go home again and all that.
> Digital is endlessly flexible
Not really. Analog electronic instruments are based on non-linear feedbacks loops. Those are pretty much impossible to emulate digitally without emulating actual electric circuits and current flow.
(Yes, I know, irrelevant to the vinyl discussion.)
I used to think that, and indeed a computer can run any equations you want. However with analogue you're getting a bunch of interesting-sounding equations without having to think of them and write them down, and that's the "analogue sound." Analogue circuitry isn't a perfect math processor the way digital is, only an approximation, and the deviations from perfection are useful.
Especially if you get into synths. A digital sine wave oscillator is doing sin(time*frequency)*gain. An analogue one is designed to produce a close to perfect sine wave at a certain set point, but you make it able to be varied around that set point by replacing some of the components with adjustable ones in somewhat ad-hoc ways, and see what it sounds like. The frequency may be set by a 3-stage RC circuit, you replace all the Rs with vactrols and see what happens, now the impedance changes as well as the frequency and it might affect other parts of the circuit. You may one-point calibrate it to 1 volt per octave but it won't be linear.
I'm convinced that at least 90% of "analog sound" can be simulated by taking the ideal block diagram and replacing every link with a parametric EQ->waveshaper->parametric EQ chain. Configuring those added components correctly is left as an exercise for the reader.
Jim Lill's video on guitar amp tone is an interesting demonstration. Hear how close he gets to the original with an even simpler combination of EQ and distortion:
