I see where you're coming from, but from my perspective there are MANY different kinds of "pros" out there, and many of them (probably even most of them) have no need to push the thermal limits of a device like the MacBook Pro for an extended period of time.
For people that do need to do this type of work, they have a lot of different options. They can do this in the cloud or remotely on a beefier device, they can use a desktop (Windows or Mac), or they can use a giant, heavy, workstation-class Windows notebook if they require some level of portability and little to no throttling.
