> Do you roll your own power grid?

I know plenty of people in Texas who will be buying solar panels and batteries after last winter. I will be doing the same.

> Do you roll your own ISP + telecoms network?

If I could magically get fiber directly to an IX I would gladly be my own ISP. I have confidence I would do as good a job or better than the ISPs I’ve had over the years (yes I realize having hundreds of thousands of customers to service is more difficult than a single home).
