I asked why these are illegal, people told me they would wreck the economy, i dont really know how, could u explain? 
In regular MC, they aren't renewable. On VC they are renewable, only by buying them. This makes them renewable, along with iron farms.
Technically they are renewable as they are farmable. If something can be gotten infinitely of, if it renewable, like coal from wither skeletons, emeralds from villages. Lapis is not renewable as it can run out (although its not likely)
On VC, they are banned as they have very high sell prices, which people exploit by creating farms and making millions, destroying the economy
