Okay, so then people will start to invest in gold. A cap on raw materials? Let’s keep a herd of cattle or two. And ad nauseam.

As someone from a post-communist country: when you put a limit on capital, another form of accumulating one will be created. Some people will be more able and motivated to get the new form of the value, others will be less able or simply not interested in it, some will inherit it over time. And we will end almost exactly where we had begun.

Limiting ways to accumulate wealth will not get rid of the desire to do so. Such a law will only force it to change the way it is manifesting.
