This literally means that everyone has an equal right to use it… And you’ve paid for an agency to policy it.
In pools, this means the agency can create a rule for “no dogs”. In this case, the library does not either set or enforce a rule that says kids need to be quiet.
FWIW, I completely agree with your point as you’ve explained it. I also know that complaining to complete strangers won’t change anything. Unless there’s a few librarians on here, in which case, Librarians: WTF?
The main thrust of the argument seems to be two fold - it‘s not 100% is (almost nothing is) and it costs a lot upfront (so do fossil-fuel plants). Smells like like some serious astroturfing to me
The rest of your argument? The only thing I see missing is transport. It needs to scale to global levels and be free with respect to both carbon and cash
I would recommend reading Kim Stanley Robinson for better ideas than I could ever give - The Ministry for the Future and New York 2140 spring to mind.
