You still need to make trips to your base to dump rocks.
Let’s say you have inventory and you’re making it back with 16 SS of rock. How far do you mine? Are you going to walk it back every time you’re full?
Goodbye persist and megas. For 16c?
Maybe you want to teleport? (EDIT:100c with free home). For 16c?
How many of these are you going to craft for every planet? You use AoE right? 50 - 70 SS per hammer?
Then if I walk by a machine that is, say, 50% worn out and just reflexively hit it with my topaz spanner, have I gone negative?
There’s a lot to think about here.
