Jet fuel is available for purchase at the consumer level without regulations because people have private planes.

Jet fuel (ATF or avtur) is also called "aviation kerosene" and is similar enough to diesel fuel that it can used in diesel engines. Kerosene and diesel are also readily available most places.

Aviation gasoline (or avgas) is just ordinary leaded gasoline, which was available for a long time to consumers until it was banned for environmental reasons.

Gunpowder and tannerite are available over the counter, no regulations there either.

    I don't want to get into guns, that's a special case in the US due to money in politics.

    But, ok, yeah "jet fuel" I was thinking more of military jet fuels, I was in the Navy for a while and never in the aviation industry. Though even they don't approach the energy density and instability a reactor would have. Maybe I should have said "rocket fuel" or even pure hydrogen. Anyway, point is cars could use fuels that are more energy dense, but even missiles don't use the most energy dense fuel available because there's a need to balance stability and potential for explosions with energy density.

    A miniaturized fission reactor like I mentioned or even more, a miniaturized fusion reactor like in Ironman, would have problems if sold unregulated, both in accidents as well as malicious use as a weapon.
