Owning a new car seems like a good investment. You get a bit more car than when buying a used car plus you get a bit more status. When prices of cars drop and better means of transportation arrive you would just keep your cash and use an Uber for example.

With the cow I think the problem is that many people would buy a cow to fulfil the basic need so margins would be extremely thin. People would soon stop buying cows again.

I think this would be generally the case in such a situation: Everything would be a commodity and margins would approach zero. You need only very few people to produce commodities. The majority of the population would be unemployed.

This is not a bad outlook per se, my argument is just that our current system needs growth. We would have to gradually adjust the system once we realize that there is now way to create growth any more.
