I remember reading the exact same things about .com domains in the 1990s.
The .tv premiums are essentially made for developers, not for speculators, even though many people who bought good .tv premiums have already sold them and made some great ROI.
But in many cases people don't buy .tv premiums to resell them but actually to develop them.
You made the comparison with real estate. But don't many companies rent office space or commercial property in prestigious locations, set up businesses there and make healthy profits ?
Good businessmen can make nice profits even if they have to pay a rent or a premium renewal fee. They benefit hugely from being in prestigious locations and that definitely pays for the rent or the premium fee.
