What's being "forced"? And what boundaries aren't being respected? If someone attempts to strike up a conversation and you're not interested, you can signal that. Or just be direct and say you don't feel like talking. Sure, that can be uncomfortable, but you can't expect humanity as a whole to repress its social nature just to spare you occasional, fleeting moments of mild discomfort. (And despite the wide spectrum of social inclinations -- I'm definitely on the introverted end -- I think it's accurate to say that humans, as a species, crave social interaction.)
In your ideal world, how would someone even signal they are a "willing participant" without talking to someone?
I never enjoyed Shakespeare UNTIL I started reading his plays, and now he’s one of my favorites.
The drama and stories in his work don’t do much for me, I view them more as a vehicle for his poetry (which is some of the greatest ever written). And I enjoy it more on the page than spoken by others.
I know there are at least some others out there like me! Nabokov cleverly said something along the lines of “with Shakespeare, the metaphor is the thing, not the play.”
