been diving into zapskis.com and just read Satoshi quote below regarding 51% attack

does this mean that 51% will be more likely as subsidy incentives for miner goes down?

or it isn't the case as it actually goes up even post halving since we should think about it not in bitcoin terms but in the terms of what Bitcoin can buy?

"The incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth."
