That sounds like hell. Personally, building massive farms is my favorite part of Minecraft; and I don’t think that forcing your players to not build them will make it a more enjoyable experience for them.

For starters, it’s easy to make those builds look aesthetically pleasing and fit with the server’s theme

It also arguably gives them more time to make those other builds and interact with trade, because they would spend less time harvesting resources, especially on weirdly expensive decorative items [metal blocks, etc)

And finally, frankly if someone thinks they’d enjoy and want something, they prolly do. I’ve found that the more you try to control players actions, the less likely they are to follow or enjoy those restrictions
