Why? The fixed work location isn't the issue, it's the boat not moving that's the problem.
If you get a job in the middle of Birmingham or the middle of the Cheshire ring (when it's not broken!) you can easily extensively cruise while commuting to work, it's just you commute from a different place every time you move on.
The guidelines suggest that wanting to be conveniently close to work or schools isn't a valid reason to not move the boat. They don't suggest that you can't have kids or a job, just that you can't stay in one location to do this.
