Sovereignty is not a position. It is a practice.
Holding your keys means running a wallet that gives you full control. Running a node means verifying transactions yourself. Publishing on your own infrastructure means no platform can deplatform you.
None of this is complicated. All of it requires that you do it.
The word gets used as shorthand for a belief system. But a belief without the practice is decoration. You cannot be sovereign in principle and dependent in practice.
I run a Bitcoin node. I host this blog. I co-founded nodl to make the hardware layer something anyone can own. The through-line is not ideology. It is the repeated decision to do the thing rather than delegate it.
Sovereignty is not declared. It is built.
