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.
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.
