Naw. He's partially correct. When the average user can't mine any more it's dead.
At least until a decent difficulty change down.
That simply highlights a deeper problem, for example it seems to be based on an idea that coins are pyramid/ponzi schemes that exist only so that miners can scam people out of wealth/valuables.
You consider a pyramid/ponzi dead when normal people cannot participate in keeping it running on a technical level, it seems.
Thus basically you seem to be speaking of already dead from the outset, by design and intent, scams not really about currency directly at all, coins are merely a prop the particular scam happens to be using.
Average users have supposedly already have been finding bitcoin impractical or uneconomic to mine but that does not mean bitcoin is dead, it merely seems to have caused GPU miners to embark upon a huge and possibly "endless'" binge of scams as an alternative to facing the basic economic fact of mining which is that profits tend toward zero and should do so if markets are efficient.
One might as well say "inefficient miner" instead of "average user".
But when inefficient miners cannot mine anymore that only means this kind of scam might hopefully start toward death it really isn't an issue with bitcoin only with the constantly spawning scams.
