I use the paper for other things once they rip from use.

Assume I get 4 reuses out of a paper bag, and I use 4 bags per week. I don’t think I could replace 4 bags worth of paper per month that I would have bought otherwise.

They can then be recycled.

True, but recycling takes water and energy. You’d probably still going to have to use them yourself a fair few times to make it a net positive.
