Help me understand why you think you have a Freedom to Smell Nice Things? If you were to file a nuisance complaint for "bad smell next door" (the action one can take in my locality), would you base it on this so-called freedom? If this person is following codes/guidelines for composting, wouldn't you be the Karen in the situation? Does this difference in lifestyle - your viewing the neighbor composting as a "bad neighbor" - come down to differing values?
IMO, this Freedom to Smell Nice Things does not exist. Cities smell, sometimes good, sometimes bad. Suburbs too - my suburb offers no compost service, and everyone's garbage composts in city-provided bins...it stinks. You suggested going rural, but that seems a romantic notion - the winds are your neighbors and the smell can often be worse than the city depending on where you are located.
