That doesn't really work in Manhattan. You may use your bit of sidewalk more than almost anyone else, but in terms of the fraction of total use, you are likely less than one percent. Hundreds or thousands of people walk on any given stretch of pavement every day. To say that the owner of the adjoining property should have the right to impose upon their use of public space just doesn't scale. Your concept would work marginally better in an exurb where almost no one uses the sidewalk, but even there, it's not really workable.
