No. Extreme decluttering might be. Just as some people have reasonable stocks of supplies, and some people are hoarders.

People can have a lot of clutter in their homes, but not be hoarders. Hoarding involves saving things like trash, and also not being able to let anything go. Many people with a lot of clutter in their lives just need a bit of help letting stuff go; they don't cling to trash and endanger their family's health and safety.

Same with decluttering. When I read the Marie Kondo book, where she talks about getting rid of her siblings' stuff because it bothered *her*, not them, I have to admit my first thought was, "Gee, she has a problem there." It is one thing to be bothered by having a lot of stuff. It is another if you can't deal with someone else's stuff in another room that you don't ever have to look at.

There are extremes at either end of the scale that aren't really healthy. One is more socially acceptable than the other, but it can still be a problem and people might want to seek out treatment for it if it is interfering with their quality of life.

Several of the people quoted in the article admit that their extreme minimalism causes problems for them.
