I see no other way to fix it that would be less detrimental, me myself would rather prefer it to tax me 5% (or, lets go for 2.5%) whenever I list something, get the 2.5% back whenever I sell something and remove the 5% tax all together.
With 2.5% and the return, you'd be able to relist your item three times if we assume that you get it sold the third time you post it, compared to the 5% tax that's in place today, while also solving the undercutting bots.
