It might be typical and expected but that doesn't mean it was desirable even then. People lived that way because they had to. It was always considered a difficult way of life. It's more likely that people gave it up as soon as they could when they had the chance.
I think there are two different concepts here. You can be materially minimalist, i.e. you can refuse to buy superfluous consumer products that are pushed by marketing etc. You will still need housing, healthcare and transportation (assuming that you have to drive to work). Those things have very real objective benefits and their widespread adoption can't be explained with marketing or social pressure. And you won't be able to get those for 100 dollars a month (correct me if I'm wrong). If you are foregoing those as well you're not just materially minimalist, you're basically going off-grid and abandoning civilization altogether.
