At any given individual event, yes. But if there is any abuse, it is easy to change said entity.
What I have in mind would be that we can take all these separate functions performed by a large company and break them apart. A centralized organization could be broken apart, but that would require a lot more political power than by simply designing up the system in a way that all functionality is spilt and has to conform to a specific interface.
transfer fees… more expensive
Are you talking about the blockchain fees or the ones established by the “smart contract”? If the former, those can easily be avoidable by using a separate blockchain (specific for the use case and backed/supported by the participating venues, which would be glad to pay anything reasonable compared to the racket run by Ticketmaster), or like I said, not even use a blockchain at all and just stick with a permissioned consensus system.
