One way to rephrase your question would be to take a look at the sum total of commodities markets, specifically the subset that includes natural resources (specifically precious metals) mineable on mars. How much of that market is bottlenecked by supply?
You can apply this approach to more complex commodities to theorize about the upper limits, but I think this is a good way to get started.
