Buying for resale doesn't magically create TP. The amount of TP available to consumers is the same, the amount of money made by TP producers is the same. But consumers have to spend more money, because there's a parasitic layer of resellers introducing friction into the system.

I would rather people buy to resell, than buy to hoard "just in case". The former does increase the amount available to consumers.

I would rather people neither buy to resell, nor buy to hoard "just in case."

"Buying for resale" could include buying up now-useless stocks of institutional TP/hand sanitizer and re-packaging it for consumer purchase. Supply increased and value added.
