This is trivial and solutions exist in the wild already. If you buy tix for the Paris Olympics, you can transfer them to your friends or you can assign their names to the tickets directly.

The interesting mechanism there is that you can buy a lot of seats at once, but you don’t get to choose where they are exactly, only the section. So in every case you’re going to have people buying big lots of tickets and distributing them to friends and family after the fact.
