Interesting question. It made think of another situation.

How often would CK have to perform to make scalping essentially a non-issue?

More than once a year I would guess. But once a month? Every week?

What factors determine this?

It would be determined mostly by price, and this would just be another version of the supply/demand curve. If he sells the tickets at $20 each, then 100k will want to see his show. At $50 each, 10k people, and so on.
