"cooling a living space is always more costly than heating a living space" Man I wish this was true but it definitely isn't in anyplace that gets significantly cold. Heat pumps are super super efficient at cooling but they get less efficient at heating the colder it gets. Humans and appliances create a pretty negligible amount of heat.

I thought any place that is significantly cold can still dig underground and at some point you can get enough heat to run your heat pump?
Right, but that's expensive too (initial outlay and maintenance) and needs to win a lot of efficiency before it pays off.
Yeah, if you have a bare minimum of 30k burning a hole in your pocket and enough open land to drill the well with the correct geology, and the larger your house the bigger/more wells you need as you're drawing from the Earth's relatively constant temperature. So the only way to get more heat is to get more surface area for the coolant.
Some people on reddit are reporting quotes of 125k for larger (>3000 sq ft) houses.
As someone who lives in a 4-season environment that can get down into the single digits F on occasion in the winter (forecast to be there for a couple of days next week), and has an air-source heat pump, I just suck it up and eat the $400-$500/month heating costs for the auxiliary (electric resistive) heat in Dec/Jan/Feb. If someone gifts me a ground-sourced heat pump I'll gladly accept, but I've got kids to raise so setting aside money for one is a long way off.
Heating is more costly if you use technology created for cooling. When you try to cool a cold space in order to heat hot space, you will have a bad time. You could use electric heater for heating, it should have no problems with heating, but will use more electricity. Or you could use something actually cheaper, like wood or fossil fuels. If you use more expensive method (like electricity) it will be more expensive.
This might be true for you. I have lived with free wood for heating and it was more expensive for me than using a heat pump. What is expensive depends on a lot of factors, political, social, location, time and knowledge. It is not a clear dollar per delta T.
Chopping up a tree is kind of fun, we bill that to the entertainment budget instead of the heating budget. And it usually happens during a hotter season, so I might have to go inside to take a break, get a cool drink. So, we can bill some of the tree chopping activity to the cooling budget!
