'Fairly allocating a severely undersupplied stock of tickets without allowing the price mechanism to arbitrate is very hard.'

This is part of ticketing. This is a challenge. So ticketing isn't easy.

Plenty of events, in fact the vast majority of them, don't suffer from this undersupply.

That's very true. But it's true for many fields that most of the difficulty/challenge/complexity comes from a relatively small proportion of the cases.
