What percentage of your time spent sailing is done as close to other vessels as you would be sailing through a modern marina?
Sailing into a slip (for practice) is more of an unnecessary risk because you can get into your slip without sailing. You can't go sailing, however, without sailing. Sailing is necessary for sailing, whereas sailing into your slip is not necessary for getting into your slip.
While you don't have to
go sailing, by choosing to go sailing you're not risking other people's property unless you make one of a variety of other choices indicating poor seamanship.
Hopefully this should clear up the confusion around both "unnecessary" and "risk".
Before you say "What about racing?" note that everybody involved in racing knows the risks in advance, whereas it's not fair to expect your marina neighbors to know that by putting their boat in a marina, they risk having somebody sail into their boat while practicing sailing into their slip.
In fact, I think we put our boats into marinas because we assume that marinas are safer than anchorages, and that when boaters navigate the marina, they will do so with a level of precision control over their vessels that they don't normally exercise on open water. Your post, and quite a bit of the sentiment in this thread, seem to forget what marinas are supposed to be about.
