It will allow people that were willing to pay the market price actually buy the tickets. If there is sufficient demand then maybe a Burning Man 2 festival makes economic sense, or increasing the supply of tickets for Burning Man itself.
We live in a world of limited resources not of good wishes. Good wishes lead to dead weight losses. I don’t see a possible scenario where price control is a good idea - LAW of supply and demand.
If there is some societal interest that the market fails to protect here (is Burning Man a fundamental right applicable to a certain type of person?) If so, then we should have a BMPA (like the EPA) formed to regulate the event.
Intellectual freedom cannot exist without political freedom; political freedom cannot exist without economic freedom; a free mind and a free market are corollaries. - Ayn Rand
Less is more.
Ockham’s razor (the law of parsimony, economy or succinctness), is a principle that generally recommends that, from among competing hypotheses, selecting the one that makes the fewest new assumptions usually provides the correct one, and that the simplest explanation will be the most plausible until evidence is presented to prove it false.
