I don’t even think having a valid license is a reasonable requirement. I should be able to own and register a car without having a license.

I think you can do this in most states; I know you can in my state (MA).

It's actually possible to own a vehicle without registration at all, though they will side-eye you sometimes.

The most common is "farm implement operated incidentally over a highway".
