Really, all this post is is the author telling us he has disposable income. Price factors into what is "best" for people; for him, less so. For others, even less so. Kim Dotcom spends $100K on each bed mattress[1] in his mansion. Kim Dotcom could write a blog post on the topic and it would sound exactly the same but with larger price tags.
There is no point at which you will be complete. You cannot perfect your existence with material things, no matter how much time and money you pour into selecting them. There is a hole, but it is not a hole you can fill up; it is a singularity, which grows as it is fed. You must learn to live with the hole.
(Note: I deleted my own post because it was downvoted once, despite getting a number of upvotes before that. It's my policy to delete any comment that gets a downvote, since that's a signal from the community that my contribution isn't wanted.)
It's a signal from one single person, not "the community".
It's not filling a black hole, but satisfying a concrete need.
The key point is not getting attached to those tools.
