Earlier quoted context omitted.
Because this is your area of expertise, can I ask you why more registrars are not selling 10 or 20 year domain ownership? Who wants a domain for just a year (if you agree with the premise behind individuals owning domains in the first place)? If I could buy a domain for 50 years, I'd do it.
We already have enough sleazy domain squatters holding names for years and trading for ridiculous prices. Instead of long ownerships, we should have some way to prove you're actually using the domain after a certain number of years.
And now imagine the public outcry that can happen every time people have their domains taken from them (rightly or wrongly).
No, no registry wants to be in the business of doing that. You continue to pay for the name, it's yours.
