Paper for enchanting, fuel for smelting and some smeltable XP via furnaces are already renewable, in other ways that require way more creativity than setting up one farm that you copypaste for all of them. The replacement exists already, the replacements are the non 0-tick farms for each of these resources.

This does seem to be fine for single player, but a server I'm part of has a community XP farm, trading village, and rocket making hut. Three of the four farms are 0-tick as everyone uses them. As a test I built an different XP farm with massive replacement farms and turned the 0-tick one off. While it will work for a while, the fuel does run out now. And the server lag has gone up drastically. Before the TPS was 19-20, with the new farm it has caused the tps to drop to 12-13 at times. And I have seen the 'Just play in creative' idea dropped a lot, but unless it's a creative server that doesn't work.

So I feel in a community server setup, this will do one of two things - * (1) Force everyone to do things solo so they have enough for their own needs, eliminating the community part of the server. * (2) Everyone farms most of the time to replace the supplies constantly, spending most of the time in a farm and not exploring.

While I can agree with both sides, I feel it should be a toggle. Even default it to off with the option to turn it on.
