implicit assumption that having things closed one day a week is bad.

It is perhaps less convenient, but that doesn't make it bad. Lived in an EU country until recently, where everything is closed on Sunday. It makes that day much more restful, and it doesn't take long to learn to get your shopping done on Saturday.

Also, it is still illegal to use power tools outside on Sunday. Which means you aren't disturbed by your neighbor's leaf blower.

Honestly, I prefer 1 day a week of true rest over more convenience but never a true rest.
