been thinking about this for a while. glad i'm not alone. 
in a way, all things become store of value. the AMM itself will be medium of exchange and unit of account will be an archaic concept.

it likely won't work like that at scale: we'd need asymptotic liquidity between all things for any one thing to not have utility due to its liquidity -- that utility due to liquidity is what 'money' is. 
we can't have asymptotic liquidity between all things but we also can have *enough* liquidity in more than just USD.

you'll also have a few dominant assets as quote currencies -- basically the role that ETH has in AMMs. 
in large scale, instead of USD dominant it'll be prismatic: multiple national currencies, tokenized commodities, dominant quote currencies

in small scale, it'll be baskets as you described. i can hold whatever i want, pay the merchant in whatever i want and the merchant will receive whatever they want. payment systems will be built on AMMs. you can actually literally specify the address of the recipient in a uniswap today -- it's all already there.

this is actually well aligned with geo and macro and probably most aligned with Zoltan's Bretton Woods III. 
geo-relations are directionally headed towards multi-currency -- at least RMB. russians seem ambitious too. 
herding commodities in reserves vs just USD is on the rise.
