Organization has detriments too, and will not necessarily benefit everyone.

Starting from "Keeping things clean and organized is good for you":

The first study attributes the correlation of good health and organization to the exercise you get from cleaning and organizing. You can be just as healthy if you exercise but are still a total slob, and be terribly unhealthy if you organize but direct a maid to do to labor. If you are sedentary, organization by hand will improve your health. If you are already fit, organization will not help in this aspect.

Your second source isn't reliable because of its subjectivity; people who describe their home as "unfinished" do so because they have a higher standard-―slobs who are fine being slobs don't consider a clutter problematic so wouldn't describe it negatively― and slobs can still describe their cluttered home as "restful" and "restorative" because it makes them comfortable. Incongruence with your desired organization and reality may increase stress, rather than simply messiness alone. If you simply prefer a messy home and find it cozy, don't jump so quickly on the board to cleanliness.

Your third source appears to be used effectively, and I'd like to mention the benefits of clutter to bring in another perspective. One study (DOI: 10.1177/0956797613480186) shows that just being in a messy room rather than an organized one increases performance on creative tasks and willingness to try new things. Being in an organized room has its benefits and its limitations.

In tandem with the minorities in the survey you mentioned, it seems as if organization is certainly suitable for those who feel happy organizing or prefer conventions, but is not for everyone. If you're a messy creative who is already healthy and feels comfortable as things are, you may be fine as is.
