If you actually look at what you get for your money, X-Wing is not cheap. The average blister contains what?
1 x Ok quality pre-painted mini, base, stand, cardboard tokens and cards?
But this is moving the goalposts. You initially asserted that X-Wing isn't actually cheaper than 40k. You then provided an example in which X-Wing was in fact significantly cheaper than 40k. You're now claiming that's irrelevant because you don't get much with your X-Wing purchase and that this means X-Wing isn't cheap.
The most expensive list possible is a red herring. Yes, you could spend $800 on a terrible tournament list if you really wanted to. So what? It might be interesting to compare that to the most expensive 40k tournament list possible, but still not really relevant, as neither have anything to do with the considerations of people who are making real purchasing decisions rather than engaging in a deliberately absurd exercise.
