I know this dumbfuck is banned, but I'm sure it doesn't take a genius to understand that object permanence in saved states, especially cell based, has little to no impact on processing power unless your engine is absolute shit. Only a broken engine will force new physics calculations for an object that's standing still in the game world, since it's position will be sorted (X, y, z axis).
This shit has been done before by AAA games (RDR2) and Indies (Project Zomboid) successfully. Hell, in No Man's Sky, your mineral extractors not only stay in a designated planet within a universe with 18 quintillion, but they also extract while offline. It doesn't make your CPU crap out just because an object exists somewhere permanently, nor it breaks the game when you finally decide to go back and collect.
Another shit take by the banned bot that pretended to be smart.
