Good comments Rich. To me, It is sort or analogous to big tractor trailer trucks. You look at a Kenworth or what have you and it may have a 425 horsepower motor in it. Then you think “hey, that isn’t so much, my Camaro has a 425 horsepower motor. Why not just use my engine in the semi”. The fact is that you could do that. Only it would have to run at 7000 rpm to produce that power and would soon give up the ghost, whereas the big diesel engine would happily run along for year upon year. Sort of the same thing in tool motors. Induction motors on stationary tools are big heavy things that hum away quietly for a log time. Universal motors are noisy obnoxious things that tear up more quickly, but have a much higher power to weight ratio thus making them suitable for handheld use.

Although, a lot of the smaller portable table saws also use universal motors for the same reason. So they pretty much did strap a circular saw into a table frame.
