I'm honestly not sure what you're trying to say here. Asset classes rise and fall against one another in cycles. You can price one asset (like crude oil for example) in terms of gold (instead of dollars). It's a ratio which keeps fluctuating, and this occurs between all assets. So certain things can be worth more or less than other things at any given point in time.
Right now food grains and precious metals are leading the pack (ie. rising at higher percentages than other stuff like real estate), because the demand is higher.

What something is worth is determined by the market, yes.
