I'd argue the opposite, consumers need more resolution than pros.

A pro will show up with a 300mm f/2.8, a tripod, a camera with good AF and high ISO, and the skills, plan and patience to catch birds in flight.

But all that stuff is expensive. The consumer way to approximate the lack of a good lens is a small, high res sensor. That only works in bright light, but you can get good results with affordable equipment in the right conditions. Greatly reducing the resolution is far from optimal when you can't have a big fancy lens to compensate.

And where is focus the hardest? Mostly where you want to have high detail. Wildlife, macro, sports.
