With solar prices hitting negative rates for some periods in a day capturing carbon and converting into burnable fuel will probably start making sense in the next few years.

As long as there's still fossil fuel powered transportation, it would make more sense to use that excess power to charge batteries, since that converts electricity into motion more efficiently than taking the detour through synthetic burnable fuel.

Destroying fossil fuel powered transportation then replacing them with electric would actually produce more carbon. All new transportation should be electric but the already running transportation if can be run on captured carbon would result net carbon decrease.

Think we could frack with corn syrup? Inject that carbon back into the ground?

Not corn syrup. That takes way too much CO2 and water to produce. Not even corn itself I suspect.
It's partly the problem alleged marshland and forest sequestration schemes face, alongside the assumption they're going to grow well in the changed climate.
(Limited experimental data suggests this works up to some 500 ppm as long as there's excess water and minerals. If the conditions are bad you lose capture potential. And what do you do with the methane releases from these systems? It's much more diffuse than from landfills.)
