Actually you don't want that either. Look at the iPhone app store - most applications are simplistic because anyone can write and sell an app and make tiny profit.
If there was a higher barrier to entry fewer number of developers would chase after the same pool of users, so they would make a bit more money and would be able to invest into making their applications more feature-rich.
I think that if there's truly a valuable market there that people will be able to charge a premium for quality products. Granted stuff like the Virtual Beer might not ever cost anything but I think well produced games might have quite a future, for example.
Apple certainly is not doing anyone any (long term) favors with the app store as it stands presently, as it doesn't feel like there's a good way to develop your own brand within the store. It would be funny if this was the invincible iPhone store's undoing. :)
Of course there is value in a good game, but who would develop it? There are too many games already and about 50 new games shipping every day. It's impossible to stand out on your own merit, no matter how good your game is, and therefore people will not be inclined to invest efforts.
It's the crisis of overproduction, bascially. It benefits noone.
