That's rubbish, the restrictions are obviously there to impede our progress (solo or not it makes no difference), the big problem is that in doing so they are making the game less fun to play as DonC said.

I don't know any other MMO out there that actually restricts its players from playing and enjoying the game.

Sure there is very little content to do right now, so the best we have is leves, quest, behest and grinding the last of which is miserably boring.
