Few in Europe can afford visiting these "free" Norwegian restrooms.
Norway has everyman's right, so for some holidaymakers that means no accommodation costs. It is also popular to do one's grocery shopping on the Swedish side of the border, or even drive up from Germany with a full load of food for the length of the holiday.
Almost everybody can afford it if they really want to.
Not thinking something is worth what it cost doesn't mean you can't afford it.
I think the hundred of thousands of tourists packing the roads all summer didn't get your memo.
You can do expensive vacation or cheap vacation, and both are possible in Norway. You can get a cheap flight and sleep in a tent, or you can drive your car through Sweden.
Or you can fly in and stay on expensive hotels.
