My point is that with technology advancing, the total theoretical amount of energy we can use is at least the Earth's mass. This is predicating on technology increasing of course.

Energy density can't be ignored here. Fossil fuels are definitely finite, and few things match their energy density and general utility. Our environment is warming, and we need to bootstrap ourselves onto other energy now, while we have fuels and quick or we may find ourselves energy constrained and fighting the battle in a far less livable place.
