Here are the relevant quotes, and here's how I understand them:
1. asserts what minimalism means and is -- that it is an objective standard. Relevant quotes:
I disagree that minimalism *means* lowering your quality of life for an emotional reward.
In minimalist circles, minimalism actually means simplifying and finding your personal balance -- to break the cycle of consumer culture, become free of the burdens of stuff, and to provide opportunities (financially and otherwise) to do what you want to do with your time/money (life).
Thus, you would even be considered a minimalist -- since you take this simplicity approach. Though it is true that some people (minimalists) have abandoned the term minimalist in favor of "simplicity" and "simple living" because they do not like the "i'm more minimalist than you!" process (ie, being told that what they have isn't "necessary" and that "true minimalism is X").
2. anyone who practices minimalism (by Him's definition) is mentally ill.
True, but just because an individual has fewer things doesn't mean that their process was rash or irreversible or causes them suffering. That's where the illicit conversion comes in.Emotionally making rash and irreversible purges of personal belongings can't be healthy, any more than hording or puking up your dinner to lose weight.
Your friend purged his life of stuff.That's socially and psychologically very different from what the OP and my friend were engaged in, which is far more like putting a finger down your throat because doing so makes you feel you have control of some part of your life. The results are superficially similar but categorically very different.
Op has purged his life of stuff.
Your friend was mentally ill, therefore the OP is mentally ill.
The trouble is this -- the lack of stuff doesn't objectively point to an irrational, mental-illness process.
If I lived on my own, I would very likely live like the OP. Why? It's a matter of preference. Although, I would have had only *one* suitcase of clothing. So, I might have been more minimal there.
This is not an indication of mental illness. It is the same process that you describe above about happiness, etc. Truly. You might not believe it, but going for less than what you (subjectively) consider "balanced" does not automatically equal rash decisions, lack of utilitarianism, lack of safety, and lack of happiness, or mental illness.
