Yeah, it isn't impossible. However, I expect there would be a radical rethink of food supply chains. This would likely include more grocery stores adopting the Aldi/Trader Joe's model of fewer brands and selection of product since the cost of differentiation gets borne more by the store. There would likely be an increase in public markets with several vendors as each vendor is effectively a brand of food.
I think enshittification will hit and don't grocery stores will either stop offering container sanitization as a service or will start selling the service independently and incorporating the higher cost in shelf products. Grocery stores operate on thin margins, so I expect this cost to get transferred to consumers somehow.
I also think a lot of existing companies will fight this tooth and nail as their bottling and canning lines provide a massive barrier to entry for competition. I also think a lot of customers will fight this since it radically changes how they shop.
The UK's privitizaton model was crap because it mandated service and only allowed operators to compete on price paid to the UK government, ensuring that all operators were lowest bid and trying to spend the least money on running trains.
Divorcing running trains from maintaining track seems to work better on price since railroads owners are more incentivized to have more trains run on their tracks to gain revenue. However, this system seems to only be tested on rail systems with competent rail operators, which DB is not.
I do think that divorcing owning the tracks and owning the trains is something that should be forced on American rail companies.
