I can't entirely agree with this.

Yes, it's easier to move if your job is completely remote. But for many people, the most significant barriers are not financial problems but mental ones.

Even though I'm single, I have few friends near my house and am satisfied with my current living environment. It's a bit scary to move to somewhere I don't know. And if I lived with a family, it would be much harder.

That's why the house prices are skyrocketing even though more people have started working entirely remotely. The majority of remote workers are still living in a big town and don't plan to move to the countryside in the near future.
