You can't legislate away stupidity or recklessness.

In my area the government quite successfully legislated away a lot of
non-seatbelt wearing.


The only sure-fire way to prevent people from "wasting air" is to make
sure air is not a common resource, and that people will not be able to
breathe air they do not own.

That would be entirely unworkable.
