That assumes everyone experiences heat and coldness the same which isn’t the case. I for example need around 20 degrees to feel alright in warm clothing. But on the other hand I am fine in around 43 degrees in the summer and wouldn’t use any AC below that.
Also young kids and older people have different needs as well.
If you wanted to regulate this, the time and money needed to care for everyone who get an exception from this rule could likely be used instead to heat everyone’s home.
