> Having only fun things to do make them obviously boring.
This doesn't really pan out the way you think it does as people can always choose to do boring things if they want (if there's even any truth to your assertion). Unless your argument is something along the lines of humans need to be forced to do things they don't want so they're able to find fun in anything, which I think is pretty... wild.
I do think humans need to be forced to do things they don't want. You don't need to believe my words. Just watch how many people get bored in their long vacations.
If all you do is having fun, it's obvious you'll need a new bar over and over (which is literally happening nowadays).
