You’re assuming people have similar desires.

Even in human relations it’s dangerous. I for one don’t want to be treated the same way someone into BDSM wants to be treated. I don’t want to avoid cooking or turning the lights on (or off!) on a Friday night but others are quite happy with that.

If you assign that morality to a species that isn’t the same as you that’s a problem. My guinea pig wants nothing more from like than hay, nuggets, sole room to run around and some shelter from scary shapes. If they were in charge of the world life would be very different.

“Live and let live” might be a similar theme but not as problematic, but then how do you define “living”. You can keep someone alive for decades while torturing them.

How about allowing freedom? Well that means I’m free to build a nuclear bomb. And set it off where I want. We see today especially that type of freedom isn’t really liked.

Usually the quote comes in a positive light. We won’t make a law/rule around it, it’s a principle so it’s meant to be short. So yeah you could argue about anything in any way you want, positive or negative. And if you want to be really precise then you make a law but it’s so precise it won’t cover edge cases. Don’t you agree that the baseline for most humans is to be in peace, find love, patience, joy, kindness, mildness ? You can manifest any of those traits to any stranger and you’ll likely have a positive impact right ? That’s the context of the Golden Rule quote I guess

That's not the human norm though. Doubt an average human way of existing is literal torture for some obscure number of people. I think you're missing the forest for the threes with that BDSM example. You can always find isolated examples as counter-argument for basically anything, but in reality that's an obscure number.

Due to the complexity of our reality a lot of things find themselves on a spectrum, but in numbers things are pretty clear.

Nothing is clear with humanity. The very first thing we do as a species is dehumanize anyone we disagree with.
