Interesting. So you base the value of an item not on supply and demand (or perceived value to you), you instead base it on the cost to produce said item. That must mean when faced with two movies you'd like to see, you go online and look up the production costs of the two movies to determine which one you'll be watching. That's an odd way to choose a movie, but then I'd be willing to bet you don't choose movies this way.
The truth is you have been conditioned to accept the $10 fee for a 2hr movie, so you pay it. If movies cost $5 one week and the next they cost $10 people would flip. Also check out the price of movies vs. inflation:

If you care at all about the cinema you must buy popcorn (which is marked up over 1000%) because they make very little money on the movies themselves.
Not that it's relevant, but you have no idea how much it cost Supercell to make this game. You don't know how much the servers were, how much their office space costs, how many developers there are, etc. There's a good chance it cost more than the $30,000 it cost to produce The Blair Witch Project, which people happily paid $10 to see.
For me, my choice to buy the builders was based on the demand that Supercell created by making such a fun and compelling game and the supply (they are the only ones selling gems). Funny thing is the fake gems mirror real world ones. Look up the fake scarcity surrounding diamonds, which people pay outrageous sums for.

Either way, calling it rort is very insulting to the people who did pay. You may not feel it's worth it, and that's fine. $40 for me on this game was totally worth it as I play it quite a bit. I certainly have gotten more value out of it then I would by seeing 4 movies. Yes it's more than the initial cost of most other ipad games, but most of them suck. This one is damn fun and seems to have a committed development team that at least communicates with the players.
Even if the 5th builder cost $1000, I wouldn't call it a rort...it's just that my demand wouldn't be high enough to warrant forking over the cash. Although if I were a billionaire I might, who knows.
