The problem with extraordinary claims like this, is that you’re much more likely to be estimating your own productivity incorrectly than you are to be correctly. There’s no doubt that most people would write more LoCs sitting a in quiet room undisturbed, but that’s likely a rather poor measurement of your ability to productively provide value to your employer.

I worked with a guy recently who was a notoriously poor communicator. He’d spend 4 days/week WFH, would barely give any updates on what he was doing, and was in general incredibly hard to get a hold of. He did write a lot of code, and most of it was very high quality. But almost none of it was ever used. His excellent code would almost never end up solving the problems we needed it to solve, or provide the functionality we needed it to provide, and nobody ever learned anything from working with him and his very senior-level skill set.

In my experience, people who make extraordinary estimates about how much more productive they’d be if left to work on problems alone are much more likely to be similar to that guy rather than the person you’re describing. This person was a rather extreme case, but I’ve worked with plenty of people like him.
