What should happen with the proceeds of the sales?
Is the highest bidder really the best custodian of a tld?
Why have a quota of, as you say, 250 every 10 years? What does this do to help, what issues does it address?

Those are not particularly compelling examples in favor of such a thing.
The issue would occur in the suggested system when ICANN decides to one day stop creating 250 domain names down to 25 domain names or some such change that increases the value of the gtlds to ridiculous numbers only the wealthy/well-connected can afford.
