The problem, at least what I've run into is primarily East Coast of Florida and more related to what I call the "New York Expat Set" than any other group. They seem to feel that their riparian rights go to the far shore and they clearly don't want other boats spoiling their view. Granted this applies only to a small minority, but they are vocal and beat on the local politicians. I could understand this if there is a flood of true derelict vessels or run down looking boats being used as long term living space while at anchor and giving the appearance of not using pump outs. The truly run down and worn out boats seem to congregate in a relatively small number of harbors while most of the better anchorages are fairly free of them.
My experience has been being yelled at to move, or having the marine police called to evict me before the anchor has had time to set in a place that has perhaps one or two other boats at anchor. Three days I can live with and unless the weather is threatening we are ready to move on. Even with Florida state trying to bring sanity and order to all of this, it seems the local jurisdictions are dragging their heels with the wealthy waterfront types leading the charge. There has been progress, but it is slow and only time will tell.
As to the Federal Government getting involved - I don't see it, they have given up on protecting the right to navigation and control over navigable waters. The Feds seem to be more concerned over holding tanks, bottom cleaning and other rules governing boats. That and their involvement in permitting construction/dredging which is more USACE. Actual use of the water by pleasure craft has been abandoned to the states to solve.
