Edit~hey gang, when I posed this question and had some opinions. I realized I don’t really feel one way or another about it and I can’t really articulate a stance (probably just too tired). I won’t be engaging. I don’t want to just delete it though because some people made interesting points. Up to mods what to do with this.
It would be bad. Governments like one solution that fits all. That is impossible over geographic regions. Take the EU, rules that apply to Denmark about housing insulation would be horrific if implemented in Spain.
