Both Japan and Sweden were very hesitant to impose legally-compelled rules compared to most other developed countries. People behaved as you described. Though one can debate whether they would have behaved even more so with an order compelling.

In hindsight, I suspect the biggest factor was not whether it was compelled, but whether people could afford it. (Plenty of payments to stay home or keep workers home were still made in Japan and Sweden.) If your rent depends on providing black market haircuts, you'll still perform them despite the ban. And if you're allowed to do haircuts, but the government will instead pay you to stay home to avoid the epidemic disease going around, maybe you'll just stay home.
