I don´t see the outcome that clear, but I get that it is game-theoretically rational to hold legacy. Even if SegWit after a hard-fork goes on for "ever", with P2PKH type addresses you will sit on every subsequent fork simply by holding legacy, anyways.

Lets take all human political relations out of the equation, then:

When the bible tought me one thing, then this: at the very moment you create "life" a.k.a. a "self-organizing dissipative structure- far from equilibrium/randomness", it will behave in a unanticipated manner.

Life is binary, either it lives and keeps on striving against perturbations and disintegration, or its dead. But what it can evolve to, this is so multifaceted. With Adam/ the Genesis-Block there was no turning back, from this point it was clear that Bitcoin will never scale, but same as with all fractals, their properties only become clear when you let them evolve.

So I don´t get the following: I don´t see any scenario where neither SegWit nor legacy can become Satoshis Vision. I don´t see any scenario where we don´t have to migrate to a completely knew system. Even Ethereum will abandon the 1.0-Nakamoto-Type-Consensus. So isn´t a 666-Coin unavoidable? As you said, there is no Ark. Bitcoin 1.0 (any Bitcoin 1.0) and the anarchistic paradise are incompatible.
