You mentioned Stockholm as an example of being able to get a job anywhere. I am saying that this is incorrect because there can be large consequences of moving to or staying in places _like_ Stockholm. This will apply to other cities as well. It doesn't take Japan to get a significantly worse deal by not following the traditional route.
The author is looking for advice on what to do the prepare to enter the job market. That is why people are discussing things like whether to finish a degree, practicing interview questions or trying to join FAANG. Part of that preparation is looking at what you actually get for your skills. And in some places, that had a certain development, you will get a lot less for your skills by not having followed a traditional route. That is something very relevant to consider.
I will now leave the question however, because it is pointless to go on.
