Even if it's more expensive, Spacex will be able to deploy hardware when no one else can because all the gas turbines and existing power plants have been exhausted and the lead time to build new ones is 5+ years out because of the bureaucratic overhead.
If you're just building solar panels and using batteries you don't need grid approval to build it and connect it to your own datacenter. The same is true if you're wanting to just use natural gas to a large extent, although you'll have more regulations regarding environmental emissions. But you'll get that when you're trying to get a million space launches approved as well.
