Well that is not true. For example the chest behind the Set priests in Seper always has the eyes of Set in them, which give you 20 zeals when burnt. Same goes for Yogs skull in Summoning chests.
I collect those, as i rebuild my bases quite often and then have to move the altars, I can quickly fully upgrade them and again, the building cost of an altar is really low.
I am not trivializing, but compared to the game breaking issues that we are dealing with at the moment, this isn’t really important.
Falling through ceilings, getting stuck in foundations, frequent UE4 crashes, missing timers in compost heaps, messed up inventories, no direct repairs in certain benches, just to name a few weigh much heavier than saving 30 minutes, when you build a new altar.
Sure it would be nice to be able to move them, but tbh, there is bigger fish to fry
