I can personally attest that it is incredibly hard to land a solid remote based job, even if you're very good at it. I have worked remotely most of my career (with frequent visits to the office) but I still see a constant stream of people who prefer to have someone much less skilled and/or capable on site rather than take the chance and hire remotely.

Time zones, contractual arrangements and/or agreements, distance and track record mean nothing if employers are simply not willing to give you the chance. Worse, some do and require you to keep track of every small thing you do (TPS reports, etc), destroying the employer/employee trust and leaving us with painful processes that no one likes to go through.

The other side of the coin is that remote workers often request US-like salaries to companies in much different economies, which leads to an even smaller rate of success ...

Finally, from my own experience, I would never hire someone who would tell me that they would never be able to come to the office at least a few times per year (3-4, a week at a time). Just one week of in-person collaboration can bring drastic improvements and/or discoveries that lead to better products overall.
