It can be done no doubt (with some training as any other skill). And probably not by everyone (in the same way as not everyone has the will, motivation and means to, say, completely master a musical instrument or certain sport). The issue is that this way of working would be even less acceptable in 2024 than in 2003. That being said, even now there are places where you can work the way you like but the irony is those places won't be on the radar and of much interest to your run-of-the-mill career developer.
