I did forget about ASIC resistant coins. I think my general point still stands.

You're making a logical leap between intentional GPU/CPU coins and inefficiency as an explicit design goal. GPU/CPU coin developers are most likely true believers in a distributed security model. They could also own GPU farms or botnets. I highly doubt developers design cryptocurrencies while dreaming of squandering global resources.

If it's a real consequence of their actions that they're aware of, they're complicit in the continuance of that effect.
