#1 and #3 are related. They make scalping easy so they get all of their money immediately and can pay event organizers ahead of time. I personally think scalping should be straight-up illegal but business schools loove it and consider it an excellent example of helping with liquidity in a system and finding the true "willingness to pay" price of something.
It features a price discovery mechanism: you auction off M tickets to M people, the price goes up every time after M people buy and the oldest buyer is booted when the others buy, but can buy back in again. Buyers can set a “reserve price” to automatically bid up to that price.
No scalping, because tickets aren’t transferrable.
Similarly, you can disallow transfering of bearer token X but let the user sell it back to the central market maker and someone else buys it. Enforcing commissions on sales.
