Where did you get the idea I was talking about injetting gas?
Since this whole time I have been talking about liquid CO2 and referencing it in units of liquid volume?

Liquified gas doesn't stay liquid forever, as a certain underground natural gas blowout that lasted months showed, compressed gas will eventually go back into the environment.
I guess if the plan was to just release anyway it reduces ground water contamination but we are increasingly in a bad place in terms of unknowns and safety.
Water is bad enough when it comes to sink holes and seismic problems I can only imagine the long term geological consequences of rock supported by a big balloon that could pop.
Not to mention the fact that compressed co2 + water forms an acid that eats away certain rocks.
