1. Yes, it is. Government will not take the money (and I don't buy any "omg inflation" arguments, since last crisis has actually in effect reduced inflation everywhere) and even if it does - if you cannot live through bad spell on 100k you have a problem.
2. Sounds like bad reserve managment i.e. missing "money in the bank". I haven't heard anyone recommending to go for mortgage with less than 6months reserve. And you had multiple mortgages with "two or three paycheques" in reserve? Seriously?
3. Money can almost always provide time (to heal, get a job, opportunity to choose less well paid job with more / flexible free time etc.), which can (for most people) be converted to relationships / skills. If you cannot make friends / learn new things given enough time, once again you have a problem.
4. > but honestly my bills are paid and I don't feel the need to make more money than I do right now. Why take on the stress?
Does not sound like you have money in the bank. Especially considering the tiny reserve (two or three paychecks is really ridiculously small, especially when you have multiple mortgages).
