If they coupled strict speed limit enforcement with adjusting the legal limit to the speed at which people actually drive plus a tolerance buffer for speedometer variance, properly publicized the change with both road signs and advertising / media signs, and applied this change in a non-discriminatory way - then yes.
Certainly I wouldn’t support such strict enforcement with the current usual driver approach of aiming for a bit above the limit under good road and weather conditions, nor if applied disproportionately against less privileged people.
