Hi @philipma1957 ,
miners do secure blockchains,
it does not matter what device is used.
The value of a coin does not come out of "how" it is mined.
Use case and adoption gives value.

You are missing the point, he is not talking about value of a coin. He is talking about keeping gpu mining alive, and yes miners secure the blockchain but not when asic mining is a mainly centralized venture. Gpu miners allow for easy entry for people to mine crypto.
