The incentive is only you completely control your keys so it is more secure, and you can do a ton of cool shit in the debug console. That is overshadowed by the major disincentive of Bitcoin Core taking days to synch if you're able to synch at all, and now numerous internal fatal errors that require a rebuild of the blockchain which takes days. Abandonment of core for lite/online wallets is the easiest solution, only people who understand how dangerous that is put in the effort to keep core up and running on their computer.
I don't think the average user is going to care about what nerd stuff you can do on the debug console.
We need a higher amount of people running nodes that is a fact. We can't live off a small % of hardcore users.
