Lol, good that you pointed it out. The only real way is apparently only self hosting foss

Coal is a basic substance, so it is in the space. Maybe there is not likely oil or gas ( although I believe methan should be pretty much available everywhere as it’s simple substance ), uranium will be in space for sure. Maybe even mining dead stars or close to dead would be possible in the future, who knows

This means space colonization. Here is the problem: 1) either we meet sooner or later aliens whom we don’t whether they are dangerous and hostile 2) we discover we live in a simulation but still every simulation has its limits ( like maps in the games )
