Not everybody needs to live in big cities, the calm you like so much can be obtained outside instantly, any day, every day.
Plus sometimes when actually having a life maybe other days are fully taken doing something important, so its nice to have it as an option. The societies that have Sunday shopping that I ever visited didn't experience any kind of shopping frenzy during it, everything is scaled down, some shops are opened shortly, some are not at all (or some close on Monday instead).
That is all said as an European who knows very well what you mean, from various angles
It would be nice to be rich enough to afford a weekend/sunday house in the countryside at the same time as a house or apartment in the city the other 5/6 days a week.
