For a market to exist, it must facilitate trading of things that have value. When value is lost and a market no longer possible due to the environment, is that really a restriction? In other words, if the state placed restrictions on capital accumulation, then there wouldn't be a need to restrict the "financial industry" as such a thing would cease to exist. Just like how a fish market wouldn't be possible without any fish left on earth.
