Fire codes prevent it in NA for a large part. Building have specific occupancy limits, and having booted down seats has exceptions for more space than loose chairs, and businesses usually want the capability of having the largest revenue, so most seats.

Now this also applies outside as those would have to be part of their property. In most cities restaurants and the sort they are built right to their property limits, or they incorporate a patio with set seating.

So if you do see it, it’s not movable furniture, but an actual area. Now along one of our drivable Aves they’ve made compromises, picture below, I don’t hate the solution, but it’s obviously not ideal and hard to accommodate wheelchairs.

They’ve allowed sidewalks to be patios, and let some road space be made into the “sidewalk”, but it’s not a perfect solution, especially when it starts snowing.
