Where will it all end? Somewhere perfectly fine, probably. But still, I wonder about the far limits and edge cases to this logic. If it was in all cases considered preferable to mildly inconvenience you to achieve a greater goal, that sounds like the cumulative effect would cease to be mild and would in fact be a bad thing. Maybe that could be fixed by regulation regulations?
if it would be cheaper to clean beaches we would just do that. if it would be cheaper to put some manners into beachgoers, we would do that. if it would be cheaper to "police" beaches, we would do that too.
regulations also have costs, such as annoyance, inconvenience, enforcement, etc.
we will see how these will turn out culturally. (as in which "external rules" will turn into internal ones.)
