> kill all of them except .com and .org
A bit tangential, but ignoring reality for a minute wouldn't it make more sense to kill .com and .org as well and retain only the country codes (ie .us, .uk, .cn, etc)? At least it would make the various jurisdictional issues clear.
(In a perfect world, I also wish there were legislation forcing any and all local government entities to use appropriate <service>.gov.<country> domains. It is incredibly difficult to explain to the average person why a few government websites have .com or .org or other random TLDs, and the inconsistency of it all makes things easier for scammers.)
