However, hypotheticals generally assume [unless stated otherwise] negligible or no friction [rolling resistance]. And in that case the interactions of the wheels and the conveyor are akin to those of molecules flowing under a flying craft or in the water or ice under skids or pontoons on a thusly equipped craft, and they are irrelevant in the dominant force of forward thrust by the engines.

Exactly. The way the question was worded originally would result in a take-off. Then, during the thread, all these conditions kept getting added in that made it ridiculous (magic tires and bearings, materials that can somehow add incredible horizontal forces through friction, etc).
