> You cannot transfer ownership killing any value you added
I think this is by design. The domain should be for personal use - hence free.
An ecosystem with an under-exploited niche will eventually produce the behaviour that fills the niche. It's a self-optimizing system. None of this is fundamentally escapable as long as we are living organisms competing for finite resources.
A monopolist hiking prices to this extent will likely see legal action against them. That's a 20x increase you're proposing.
It's also unlikely to have a material effect. .com used to cost $75 a year back in the day, and that didn't stop squatters, and high value domain transfer sales. $75 in 1990s dollars is about $150-$190 today.
then don't allow reselling, just allow giving it back and do a raffle again
Many ways of adding friction to obtaining the updatable value - which a human owning a domain would be happy to do, but a squatter would not want to.
that's how one of my local companies tries to force clients in. They removed auth code from their web panels and introduced complex snail-mail procedure.
That was clear signal to run, but it took me 6 months to do just the domain transfer.
