You forgot the steps of pressing your own silicon wafers in the garage, followed by soldering motherboards from zero, and of course, having a steel mill to build racks and computer cases. The only way to ensure true independence.
In all seriousness, I am a big advocate for hosting your own infrastructure as much as you can, but that requires you to be REALLY into doing it. Otherwise, it's just a completely unnecessary chore.
No, that comes far later, after energy self-sufficiency, at which point your operational expenses can be minimized. Then we can start talking about going fully vertical to reduce our supply chain dependencies.
If you're concerned about silicon dependencies, I'd recommend starting with some real estate purchases (mines) and forming a Special Economic Zone first, though.
Remember this is about being an owner and not a renter. The only restriction is our recurring costs, but we have unlimited room upfront, like a Lincoln.
Focusing the wrong problem. You'll also need to own everything that being a part of a nation state provides you, including markets and defense. If you can't do that, you can't live truly rent-free.
Don’t forget creating a society capable of supporting industry and science. On a planet producing enough of the raw materials. In a Universe with appropriate fundamental physical constants etc etc.
