Or 1000 1 Carat Diamonds? Does that make diamonds good money? This is a good argument, but I think a better one would be that there is no way the seller is willing to sell any laptop for 1,000 ETH, given that the value of 1000 ETH as of writing is over 1.5m AUD. If they gave me a quote for the actual value of the laptop in AUD (perhaps 1-2 ETH?) I would still say no, because the inherent volatility in even the most "stable" coins is too high. 2 ETH might be worth 3k AUD today, who knows what it will be when it arrives, let alone when I want to spend it.
