Taking reward compensation back by fraud proofs is not enough to fix
the problems associated with double spending (such as, everyone has to
wait for the "real" confirmations instead of the "possibly
double-spend" confirmations). Some of this was discussed in -wizards
recently:

Fraud proof removes all the attacker's revenue. It's like the attacker sacrifices an entire block for double spending in the current system. I think Luke-Jr got it right at that discussion.

Best,
