so anime is expensive?
Technically speaking, no, and yes. The "No" part is that you can watch it for free. The "Yes" part is that you have to pay for electricity to power the TV to watch anime and you have to pay for the TV. Also the animators/film studio (or company) has to pay in order to air it.
Things turn out to be free even though we don't need them. But we have to look at other factors. We look at anime and think it's free to watch. But another factor is the Television, the electricity bills, and the airing.
