What would I rather, collect garbage, or let garbage pile up in my house?
Probably I’ll collect garbage.
And since I’m doing it, might as well do cooperate with a couple members of my community and clean up the whole thing.
Would I rather my house pile in shit or learn plumbing? Probably the latter. And then when my neighbor is having plumbing issues, I’ll give 'em a hand.
And not everyone has to do this. My neighbor and I decide he’ll take the garbage I’ll take the plumbing. Or maybe we both learn both, and just switch.
You seem to forget that these things were born out of a need anyways. There’s nothing stopping people from doing what they need to do to fulfill their community’s needs.
