Strategies for dealing with money seem to me to come in two varieties: Have as much income as possible and don't worry much about the outgo, or have as little outgo as possible and don't worry much about the income. It seems to me like you'd prefer the latter, and I don't see anything wrong with that.
It is a less popular kind of choice, and one that many people don't really understand, so you might always have to deal with people objecting to it, but that doesn't mean it doesn't work, it just means that they don't understand it, or possibly that they're jealous. ;)
Googling 'frugality' should get you some good advice about making that kind of lifestyle work.
I also suggest testing your assumption in #8 that you can easily make money whenever you need it by doing so in order to set some money aside in case of an emergency as in issue #7. This is actually more about #8 than #7, though - basing your lifestyle on an untested assumption like that isn't wise, and if (as I expect, actually) the assumption turns out to be accurate, having the experience of finding a job (or whatever) when you don't have an emergency will be useful if you have to find one (or whatever) when you do.
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
