Hydrocarbons didn't form themselves. An energy source is required to remove the oxygen from CO2. If it is possible to tap that energy source directly, then depending on energy from hydrocarbons is incredibly irresponsible because high concentrations of CO2 make the planet less habitable for most life including humans.

Hydrocarbons aren't just a form of energy, just burning them is arguably a huge waste. The point is that they're not exhaustible.
