Ahh, see I don't think that I will ever buy that argument, haha ;)
BTC is not as valuable as it is because it has some special status - what it has is billions and billions of dollars in buy pressure from Saylor and institutions - both of which ETH can have (and is already making meaningful strides towards!).
Assuming that logic is true, though, wouldn't it indeed be possible for Ethereum to become a "snowflake" if the narrative becomes strong enough? I don't see why it's "BTC only and nothing else." That argument doesn't hold any merit because "snowflake" status is based on nothing tangible.
I mean hey, everyone wrote off ETH at $1400 based on fees, fragmented liquidity, inefficient EF, etc etc - and then it magically pumped to its old ATH.
