Yes, but it's not going to have any meaningful impact on the overall gdp because it couldn't happen at scale (requires one party to have 1.000.000$ to spend in the first place).
But isn't this exactly what has been happening on a macro scale with the 'service economy'? We drew ever larger segments of people and activities into the world of financial transactions because of the massive amount of rentseeking money to be made in this environment. We doubled the amount of time the average family had to spend in salaried activity, and we passed start twice as now all activities that were previously selfserviced were also 'market' procured as no-one had time/energy left to take care of this after a long workday.
