Yes, but my thinking here is entirely hinging on the availability of out-of-band payments in a currency that is not btc (and expected to lose value over time in relation to btc, and also in which miners need to pay their bills--all of which are true of miners today).
If I had a dust output in Jan 2023 and I could pay a miner in fiat 2x the fiat value of the utxo to use it in a transaction that combines it with a bigger utxo, it would have made sense for me to do that.
Similarly, if I expect the value of btc in fiat terms to increase in the future, I should be willing to pay more than the current fiat value of any dust output now as long as I can pay in fiat.

Right, but I'm not competing with fee rates ten years from now, but I CAN make a prediction about fiat price ten years from now.
I only have to compete with fee rates now. And some people paying fee rates now may have a less hopeful opinion of btc's fiat value in the future than I do. It becomes an arbitrage case (if I'm right about my future fiat price prediction).
