Are we discussing lighthouse or the viability of gavincoin?
We are discussing the availability of the blockchain to support services/projects.
No, we are not. That's a different topic.
Does the availability of the blockchain to support services have priority over the viability of the chain?
That you are missing the point from the start because a blockchain that can't support services is a dead blockchain. Bitcoin is a protocol that people must abuse for different kinds of stuff. Just like we abuse the Internet for whatever we want!
