The ultimate "farm tax" in Attack on Titan is the Rumbling. It is the ultimate conversion of life into raw destructive power.
Alternatively, "farm taxes" could refer to the real tax structures that fan artists and content creators (like HforGods) face. In many countries, if you generate income from streaming on Bilibili, YouTube, or Twitch (playing games like Attack on Titan 2 ), you have to pay income tax. farm taxes attack on titan part 2 hforgods
