Yes, this is a great extension idea. If you make a model like this, for different parameters of speculation vs. value creation you can then test what the most socially beneficial rates of tax are. More tax will lead to smaller but more equal economies and laissez-faire shouldn’t be optimal. I would just want the model to acknowledge the non-speculation part, because many of the things I buy are from spectacularly rich companies, but that are genuinely useful to me.
