Technically this might be called a fork, although we are not changing any code base or so but we are isolating ourselves from the core nodes - as described - to proof a point in real life. Not just theory. Can the content survive, Most likely, yes.

And yes the deso on that isolated chain is just a number, no value.
We don't need funding in that case do we?

Decentralization is key, for any node that claims to be that.
Come discuss in Vibehut some time, we will be there.
