The state could ban on/off ramps, and ban ownership of it like they did with gold in 1933. Certainly this would crash the price as most people wouldn't want to

The state could ban on/off ramps, and ban ownership of it like they did with gold in 1933. Certainly this would crash the price as most people wouldn't want to be involved with it and risk committing crimes. It probably wouldn't kill it, but it might kill demand for a while and in any case investing now with this potential outcome crashing price in future is a risk.
