Is it necessary from a strictly technical standpoint to have a sensor the same
physical size as 35mm film? Isn't what's important image size and definition,
and if so, couldn't this be achieved with smaller sensors with more pixel
density and optics to produce
an image that fits that sensor?

I think the drive behind the production for 35mm sized sensors is to placate
those film users who know the ins and outs of film and are not comfortable with
dealing with a different system. This not only includes end-users, but camera
designers.
