The main answer seems to be `domain squatting'. Obviously this is a definite concern, but couldn't it also be solved by having TLD owners instituting some requirement to the effect of ``if you've owned your domain for over a year but still haven't used it for anything, we're taking it back''? Of course, that leads to concerns over what qualifies as `using', but I'd imagine something could be worked out.
