Max Supply / Mining Reward Question

When BCH hits the max supply of bitcoin cash in the long distant future, what will incentivize the miners to continue mining? Especially if you count low fees into the mix? I know this won't happen in our lifetime, but what would be the incentive at that point to continue to mine/secure the network?

Sorry if this is a stupid question, just a thought that came to mind that came out of nowhere, lol.
