I have made a mistake and made my walls in my base out of a relatively rare metal - obsidian - because the walls reminded me of Xbox's color.

I know its cheating, but is it moral for me to spawn a bunch of obsidian in? If I do, should I remove some other items/money in order to simulate buying it? Or is there some easy way to get it besides spamming nefia that only give like 2-3 a run at best?
