I mean they are apparently necessary because people won't stick to the universal "don't be a dick" rule; they'll argue about what defines "dickish behaviour".

And that's a good thing, no? I mean if we were happy with current state of things we'd still be living in caves. Bickering and not being happy is what drives progress forward. You want it better than current state of affairs, for you/your kids and that makes the human brain jump from riding on horseback to riding in a Tesla in roughly 200 hundred years.

Don't worry, even getting close enough to that dystopia will wipe out the society and so not that many people will be left to worry about happiness.

Every human interaction? No, it won't be regulated.

(Almost) every human interaction between a company and an actual human? In most cases, yes please.
