You know... If it's 16k total and you divide it 20 ways, $800 per person... Not insane for a playoff game. Maybe the sort of thing someone does for a bachelor party or family reunion or something.
If I was massively rich, like Musk/Bezos money, I'd buy a suite season ticket and go to games alone. Just have it all to myself, maybe nap out in the open when things get slow. Throw peanut shells down on the peasants below. All sorts of fun.
