I think there are a few errors in there. process_system_transaction disappeared?

there is a risk here that sender's balance is less than the floor, because we did not charge the floor as part of the intrinsic gas

We check against gas limit at the start and user always have enough balance to pay for the gas limit and floor < gas limit for the transaction
