How sure are we at this point that the warp core isnt just a bunch of propane?

I’ll tell you hwat. These Borg thingamajigies assimilated my propane and propane accessories.

I'll tell you hwhat, propane is a liquid in the tank, it's only a gas when it comes out of the tank. That's what makes it such a reliable and affordable fuel. That's why they call it the "liquid mistress".
