Well, I remember that in the 1990s (when Network Solutions had the monopoly of domain name registrations for .com, .net and .org), the renewal fees were much much higher than they are now. They charged $100 for a two year registration, which is twice as expensive as the current .tv regular renewal fee at eNom.
At that time, the aftermarket for .com domains was much much weaker than it is for .tv domains now, it barely existed. That was the time when you could handreg domains like business.com or pizza.com. That's when the very first domainers came into the market. Many people thought they were crazy and actually said exactly the same things you mentioned in your previous post. That they couldn't ever make any profit by doing so, that Network Solutions kept the profits for themselves in the primary market, etc. But these first domainers still held their domains, kept paying very high renewal fees year after year, and were actually proved right. Every domainer would now want to go back to the 90s and handreg those domains like business.com and others, as they're worth millions now.
Just like in any business, it's all about taking some risks. But things are already looking fairly promising for the .tv extension.
It's true that people who rent office space aren't in the property business. But if they're good business people, they can still make good profits, in spite of the fact they have to pay a rent and that they don't own the property.
What's great about .tv premium domain names is that you can be both in the "development" business and in the "property"/speculation business, which is not the case with real estate that you rent. So that's where your comparison is actually not correct.
We've seen many examples (on NP and elsewhere) of domainers making some nice profits by buying and selling .tv premiums. Obviously, this is much easier to do with cheaper premiums. But when buying expensive premiums, most people will realize they probably won't be able to flip them and usually have a very solid development plan for them (orlando.tv being a good recent example on NP).
The fact is that, just like the .com extension in the past decade, .tv has an increasingly large aftermarket year after year, that more and more businesses and corporations are developing major .tv sites, that more and more Internet users are using .tv sites on a daily basis and are becoming aware of this great TLD.
All in all, things are definitely looking much better for .tv than for most other newer extensions.
