"The Invisible Hand" first defined by Adam Smith describesOne way or another we all pay. It's the invisible hand. There is no free lunch.
"competition between buyers and sellers that channels the profit motive of individuals on
both sides of the transaction such that improved products are produced and at lower costs.
This process whereby competition channels ambition toward socially desirable ends comes
out most clearly in The Wealth of Nations"
Love to hear how you think how the "Invisible Hand" applies to paying for beach access.
The economic cliché you're looking for is the "Free Rider Dilemma", but this isn't really applicable either since administration costs of most public beaches are covered by property taxes or through Federal funding in the case of National parks.
If you're going to adopt a pay per use model for park use, and sub-divide it by additional fees based on use, then I assume you also support paid rescue by lifegaurds?
Just swipe your VISA right here on my jet-ski and I'll tow you in? Didn't bring your VISA, sorry, Bub! blub, blub, blub...
