Re-viewing things in a different light might be useful, or not: the reasons for procrastinating remains surprisingly few:
1) You have better things to do at the moment
2) You don’t feel like doing anything

1) In attempting to validate procrastination, you have, instead, proven that the value of doing things in the future depends on the value of doing things in the now. You even hit upon the realisation yourself (in your post) in identifying it as being economic with your time: performing a cost-benefit analysis of all courses of action, and prioritising some over others based on the concept of opportunity cost, rather than of procrastination.

2) Which brings me to my original point: either you’re in need of repose/tranquility (see earlier comment) or you’re “counterproductively, needlessly and dilatorily” putting off things (see (1) – being economically inefficient with your time)

I’m sorry for coming off as pugnacious! I do enjoy opportunities to see things in a different light, but I do not see the goodness in this act of self-deception.

Postponement and procrastination are related concepts but they are not congruent. Translated from its original Latin roots, procrastination means “in favour of tomorrow”. While, postponement refers to changing an event or an activity to a later time or date, procrastination, in addition to encompassing the rough meaning of postponement, also includes the psychological aspects of such behaviour.

You may be right in pointing out that procrastination strictly requires the behaviour to be counterproductive, needless, and delaying. I will have to leave that with the subject matter experts.

The intent of the article was to remove the negative stigmas associated with procrastination by changing how readers perceive such behaviour. By changing their perceptions, hopefully, they may be able to use it to their advantage just as how people may turn their weaknesses into strengths. In other words, I want readers not to associate procrastination with the three above-mentioned criteria and instead, use it to better organise their lives.

Think of it as self-deception for a good cause.

“The main constituents of a satisfied life appear to be two, either of which by itself is often found sufficient for the purpose: tranquillity, and excitement. With much tranquillity, many find that they can be content with very little pleasure: with much excitement, many can reconcile themselves to a considerable quantity of pain. There is assuredly no inherent impossibility in enabling even the mass of mankind to unite both; since the two are so far from being incompatible that they are in natural alliance, the prolongation of either being a preparation for, and exciting a wish for, the other. It is only those in whom indolence amounts to a vice, that do not desire excitement after an interval of repose: it is only those in whom the need of excitement is a disease, that feel the tranquillity which follows excitement dull and insipid, instead of pleasurable in direct proportion to the excitement which preceded it.”
