DeSantis says he would eliminate four federal agencies [the Departments of Education, Commerce, and Energy, and the IRS] if elected president

this almost certainly falls into a weird middle ground of "virtue signal that even he knows is not realistic, but which also speaks to the legitimate opinion of many Republican voters and elites probably including himself". DeSantis is many things--but ignorant is not one of them.

He would probably just pull a Comcast and rename the IRS to something catchier but more invasive to the lesser communities

Have you read any of the Shadowrun series of books where everything is controlled by mega corporations with their own private armies and pseudo slavery?

Yea... That.
