If you remove your holding time I will buy some BTC off you.
Unfortunately that withholding period is a key component of the chargeback protection scheme.
Or it just gives you enough time to transfer the funds to an alternate account or buy things.
1 day hold time will not prevent chargebacks one bit so I think this is just to give you time to "cash out" the paypal.
The only way to protect from chargebacks would be to hold for 180 days.
I advise all buyers to use an escrow with this user.
