It seems to me that you're critical of people that use strategies other than "try harder" to accomplish their goals. You are essentially opposed to the use of tools here.
I am not critical of any people. I am critical of strategies. I am not critical of non-"try harder" strategies. I am saying that all strategies are ultimately "try harder" strategies at their core, so I don't think this is a good way to differentiate them. I am not opposed to the use of tools. I am simply suggesting that one tool may be more useful than another.
You've admitted that you aren't a stranger to procrastination - is it the case that you never procrastinate or get distracted now, because you just found more willpower? That sounds unlikely to me.
I'm not sure that I ever implied that I never procrastinate or get distracted.
At any rate, if you accept that willpower is a finite resource (I haven't seen you dispute this), the real issue is simple.
At any given moment, willpower may be a finite resource, but I don't think that one's willpower is unchangeable.
At any given moment, one's energy to accomplish tasks is finite, but that doesn;t mean there is nothing that can be done to increase one's energy.
For example, your finite energy may limit the number of pull-ups you can do at any given time. If we assume that your energy is unchangeable, a good strategy to maximize the number of pullups you can do is to never do any, because it would permanently decrease the total amount you could do. But in reality, doing pullups temporarily decreases the number you can do (e.g. Once I do 10, then I can only do 0 for a while). But if you actually train yourself, the number of pullups you can do actually increases.
I get a lot more done when I focus on a few simple techniques that limit distraction, so it suggests that these efforts to conserve willpower are worth it. You might experience the opposite, but if you haven't really tried it, your arguments are baseless conjecture.
Where do I get the willpower to try it? I am making an a priori argument, so it's fine without evidence.
