There's an abundance of CPU power. Access to those CPU's is one problem but essentially why two-sided marketplaces exist. They've emerged for this exact problem in other categories (as pointed out in other comments) such as AirBNB/VRBO (housing), Turo/GetAround (cars), liquidspace (offices), boatsetter (boats).

I wonder if access was democratized, would demand increase? Jevon's Paradox in action?
