Can't they just sell access to their address?

One way or another I'd rate the odds of their still having access to that address in 2035 as pretty low.

Realistically anything that requires people to have decent data management / opsec is going to fail for >99% of people.

They could but the buyer would not have assurance that they are the only one with the private key and therefore likely wouldn't do it.
