"Minimalism" as it is described here is just a personal version of technocracy - the arrogant belief that you actually know enough to produce explicit, precise long-term plans. Kept under control, and used for shorter terms (say a year detailed, and two more sort of general and subject to change as you learn more) it can be useful; otherwise it often is just a personalized version of the old Soviet "Five-Year Plans".

ADDED: Rereading this, I think I missed my point slightly; the problem with minimalism as described here is that it locks you in too much to your current plan; it reduces your flexibility to adjust your plans as you learn more about your problem space.

You're free to change your priorities at any time. For example, I decided to change aspects of my life so I could lose weight.

We need to be aware of value propositions and how they change. No one is saying you have to lock yourself in stone. Indeed, the minimalist approach increases your flexibility; you've invested the minimum to reach your goal, so if you abandon the goal you've lost the minimum you could invest.
