The main problem is that criminals will deposit money with a stolen credit card, dump the chips off to another account, and withdraw from that account. Then the owner of the credit card will dispute the charge, and the poker site is out the money.

Chip dumping heads up does not harm anyone directly, but it makes it harder to check for fraud, collusion, and other forms of cheating, since more players have to be checked than just those who are withdrawing.

Another issue is that poker sites usually absorb fees on the deposits and withdrawals. Normally, the rake from playing exceeds those fees, so the poker sites are happy to accept that loss. If you deposit to transfer money to someone else, and they immediately widthdraw, the poker site has lost the fees with little or no rake paid.

If you have a legitimate reason to transfer money to another account, most sites will let you do that without chip dumping. They may require that the accounts be active.
