People managed to keep trees in cities just fine prior to the mid 20th century so I can't imagine it's an insurmountable obstacle. Beyond cutting the trees down, other valid solutions include (but are not limited to) letting the leaves be on the ground by the tree, using a rake, planting tree species with smaller leaves, or allowing the leaves to be picked up by the regular street cleaning trucks.

Trees are really only a lot of work if you insist on keeping a grotesquely unnatural manicured garden; the only tree I've got that's any significant amount work is an apple tree that would turn half the yard to a rotten apple tripping hazard if you didn't pick them up. A couple more need trimming every few years to keep a path clear, but I would chalk that up to user error in choosing to plant them slightly too close to the path.

Contrary to what the "just tough it out" types would have you believe, noise pollution does cause appreciable harm to public health. Making lots of noise in a dense neighborhood where thousands of people live is just not worth the marginal efficiency improvement of blowing vs raking leaves. Tangentially, this is also one of several reasons why speed limits should be 30km/h in cities to limit rolling noise.
