Gated Communities

Am I the only one that finds the idea of a gated community within the city an offense to the taxpayers of said city?  Does not the city taxpayers collectively pay for the streets and sidewalks, the installation of sewers, water, electric, and phone lines?  Does not the city police have said gated community within their jurisdiction?  So how is it that the people who live on those streets can claim as their sole property the public ammenities that all taxpayers pay for?  This is just wrong.  And seems to me should be illegal.  Those city officials approving such communities should be charged with mishandling taxpayer funds.  Just sayin.
