Well, a finer policy would probably be better, I agree. But, in this case, even if the loss of a beautiful peace of engineering is always a pity (but it is not even lost, because the source code itself has no reason to be forbidden!), I don't see really what is the loss for the world.

So e.g. if you reimplement whatever usage you found for some Ethereum contracts, in a non-blockchain technology, then you can just access it through VPNs whenever that becomes necessary.
