You're engaging in a pretty common fallacy by taking the contemporary standard, in a world full of wild inflation and funny money, retroactively applying it backwards, seeing [correctly] that it wouldn't work, and thus concluding that funny money is needed. But you need to consider the impacts of the funny money itself.

One fundamental difference is that inflationary systems incentivize the hoarding of 'things', like housing, as a means of escaping inflation. This is because the price of 'things' will always increase with inflation. But in stable or deflationary systems there's no inflation to hide from and the price of 'things' is stable or can even decrease over time, so there's no longer a hoarding incentivization for 'things.'

So you can see a visible impact of this in housing prices. In the 50s a typical house used to cost about 2 median salaries. [1] Go further back in time and you're down to 1 median salary. In modern times, we're at historic highs of a median home costing 5x a median salary, and in desirable locations like western California it even gets up to 12x local median salary for a median home. [2] That's median, not Beverley Hills.

So yes, in modern times you need endless funny money to do achieve even basic societal things, like owning a roof over your head. But that's because of the funny money. And this is before we get into realities like the fact that when the government 'prints' a trillion dollars, most all of that is going to end up in the pockets of the wealthiest of society giving them even more money to speculate with, driving prices up even more. And much more, there are endless self feedback mechanisms that have left us in a vicious cycle that's probably inescapable at this point.

Real wages are up 14% over the past 47 years [3], and we now have a trillionaire. That's inflation for you. What do you think they'll call this era in the future?
