I don't think that is the notion that "some" of us may have. More like--quiet and pristine, or nearly so, anchorages are rare and relatively distant/remote, as you suggest, and should be cherished. Getting to one and staying long often requires a large commitment of time and effort. We were near Desolation Sound, British Columbia several years in a scenic and peaceful anchorage when some goof ball arrives; makes a lot of noise getting anchored. Then, not long afterward, gets out his remote-control toy speed boat (buzzzz like a weed-eater) and starts running it around the anchorage, for probably half an hour at a time. Because of the echo characteristics in there, it was very loud.
Trailering up to a high-altitude lake for a long weekend of relaxation only to find yourself 200 ft away from a boat with people playing the radio with outside speakers throughout the day and periodically running a outside generator to keep beer cold (or whatever), etc., would be a big disappointment for me.
So, it's up to us to point out things to consider when boating. for example, try packing IPAs that you can enjoy not chilled, or else red wine. Use SunShower to heat water. Use an oil lantern for below or in the cockpit; bring AA batteries to power night accent lights; get a Bluetooth portable (12-volt) speaker for private listening aboard. Use solar panels for charging; up grade your alternator to high amperage for charging when using the diesel, etc. Keep your noise and carbon "footprints" low, etc. The basic idea is to keep up (maintain) daily your batteries near a high state of charge. Preserve the ambiance if there is any. If not, then I guess it's the old adage--if you can't beat 'em, join 'em.
