Why do we buy compost?

I’m hoping to stop buying compost. Or definitely reduce the amount I buy massively. If I get my homemade hot composter working correctly. It’s a big “if” granted.

TMTT has nailed exactly why we buy compost.
Veggie questioning why is incredibly thorough provoking. Especially at a time when peat free is being pushed for environmental reasons. Because from my very limited experience of peat free it’s no better than homemade cold composting. Probably worse as it’s full of plastic and glass (in my personal experience).
Has there been some sort of brainwashing going on to make gardeners need, want compost?
Yes there is the screamingly obvious you can’t make enough compost. This has always been my problem.

This topic is Definitely something that I’ll be thinking about a lot.
