I have a huge London plane tree just over the fence at the bottom of my garden, and I too get (piles and piles) of the enormous leaves everywhere in the autumn. The difference is that I love the tree, and although it would be nice if it was reduced in height slightly, I wouldn't dream of demanding that the owner cuts it down.
I have some sympathy with the man - I bought a leaf blower when we moved in here, and it lasted one autumn before the motor burned out because of the sheer quantity of leaves - so now I wait until most of the leaves are off, then employ someone with an industrial blower to get them up and take them away. Yes, it costs me money, but I have the beautiful tree to look at all year round..!
