I'm not sure what you're suggesting. Max's way is to at least turn food on/off so if people don't want to have to use food for camp, they don't need to. They can just sell it like all useless junk.
Mine suggests that I want to be able to make it so I don't even have to pick up things that cost less than a certain amount. For me, what's the point, and why waste my time. Just make it so I don't even see that useless junk to pick up.
I mean, really, how much money do you really get from all that crap? 30 GP every time you go to the store?
But some people might need every gold coin they can get, so they might want to pick up and sell everything. My suggestion allows for both play styles.
