I think I could also survive in a similar way.

My to-do list just helps a bit with my ability to be productive. If I'm at a loose end, I can refer to it and remind myself of X, Y, or Z that either should be done or that I'd like to have a bash at.

Without it, I'd 'float unproductively' more.

(And it's not necessarily about productivity, more about purpose, where I'll feel much better having completed a task that I'd previously set myself - like mulching the dead leaves or tidying the study or weeding the vege patch that I'd otherwise have not done in favour of 'floating' scrolling HN or whatever).
