Everybody already has an existing solution for that. It’s called buy and return. There are some system costs created by it but those are already built into the price of products you buy. There are also real and perceived ethical issues but those come down to the specifics of how each person goes about exercising (using or abusing, depending on specifics) the freedoms the market system avails them in each specific situation. I can’t think of a valid reason to dismiss this solution as if it didn’t exist.
