Because there are nonvolatile additives? Because gas is ~1000 times
less dense than its liquid? Because the Second Law of thermodynamics
exists and PV = 101.325 J/liter-atm? Because it's a stupid idea?

Learn something about cylinder combustion engineering. Learn
something about bullshit Enviro-whiner natural gas and propane
vehicles.

That is why we have engineers who can measure, calculate, design,
manufacture... and optimize.

Suppose that our fuel tank was very safe, and 100% safe from
explosions.

Instead of fuel injectors, why not heat up the fuel, and pump this
high pressure gaseous vapor into the pistons?

Currently, liquid gasoline is sprayed into the pistons. From what I
understand, the finer the mist, the better and more thorough the
combustion.

Since the gaseous gasoline is the limit to how finely you can atomize
the gas, I would think that this is the most optimum way to put gas
into the cylinders.
