I myself only accept what works for me. I am pragmatic to the extreme. I know of NO other person who fully agrees with my philosophy on life (my fundamental beliefs are VERY different from what is commonly accepted) - but that's exactly the point - that's what makes 'me' me.
Now I have offered the above guidelines for those who are already inclined to agree. I have no interest in arguing or convincing those who do not.
In my experience, people who say that have a lot of interest in convincing others. It's like, "I don't care what people think or say". It's mostly pre-emptive reply to criticism.
So, no, this is not about "convincing arguments". As with all of existence, this is about making a statement of who you really are and inspiring others. There is intrinsic value in that. I believe in leadership by example. I do not believe in leadership by "convincing arguments".
Good discussions can make you see things differently, take a new perspective that you had not fully considered before. If you only make "life statements" and never cordially exchange points of view, you lose a much useful way of changing your own; you risk keeping yourself in a warm sense of certitude, losing precious feedback from other people's insight.
If that is true your comment is utterly useless to anyone reading it.

I guess you've never had to pay rent/mortgage or had to support anyone. In the real world, your advice would get you out on the streets.
