Wouldn't this be case-by-case? That argument makes perfect sense if we're talking about a bar hosting a band, but I can't apply that same logic to a stadium whose cost was largely borne by taxpayers with the promise it would enrich public life.
Sure, but we're talking about the finals here, not a regular season game. Of course a huge number of people want to go. During the regular season I have no problems getting tickets. Demand is huge, so the price goes up.
