See, that's fine, that's less about purchasing an actual server and more paying to keep those servers running. They calculate the expenses for the server and everything else and then plug that into game cost. But in-game cosmetics that we pay for specifically aren't like electricity or food items. They don't HAVE to take them away, and then RESELL them to us AGAIN.

The problem with your argument is you're ignoring value for cost divided by time, or the fact that emotes have been obtainable for free just by playing the game for some time. If you buy something right before it expires (emotes do not have any current expiration), then your cost to value ratio is poor. If you buy something you get to play for say a year or more? You've already gotten more value out of it than the initial cost. It was always reasonable to assume buying something for 1 game does not last forever (whether it's you not wanting to play anymore, the game dying and online content not being accessible, or the content having time limitations) or carry over to the next game for free. You bought something for one game and you still get to have it in [i]that[/i] game, not both. This is a perfectly normal and sensible business action. There is nothing unreasonable about it.

I agree with you but you are wrong about one thing. You can buy the individual emote that you want.
