we've been told that one of the benefits of SC's is in crushing altcoins. if the current network effects are already doing that, and i agree that they are, that takes away a major argument to implement them.
NL's point is that this severing of the path back to BTC will create losers and thus destroy confidence, not only for the loser's themselves, but for the rest of us potentially.

please don't be so shallow. SC's were absolutely not created in order to "crush" altcoins. neither is it a "major" argument to implement them. the reasoning is that once implemented it should discourage the creation of alt-scams and refocus the energy of developers on innovation within Bitcoin's ecosystem.
lol, i guess i'm hearing things.
