Or take the approach of several European countries: tickets cannot be resold for more than face value.

Ticketmaster still double-dips on running a resale platform and charging a "processing fee" for reselling a ticket, but it means the original ticket purchased for €100 + €10 "fees" is resold for €100 + €10 "resale fees" and not more than that.

I had to re-sell my ticket, and I sold it for maybe 16% of its value, _and_ had to pay $100 - twice! - for the fucking privilege, and presumably whoever bought my ticket did too.

Double-dipping? Triple, at least.
