Read this book, THE MILLIONAIRE NEXT DOOR. It's all about maximizing Fiat, but the message is clear that wealthy people don't let others do every little thing for them. Self made millionaires repair their own things and they don't have to have huge salaries.
It's a great book. Applied to Bitcoin it will make you only call a plumber for major work. If anything you will already know a plumber who you've helped do some other things and you exchange skill sets.
For instance, today I helped two millionaires repair some work at their children's homes. We all physically jumped into the mud and did stuff. These repairs would have cost thousands of dollars but instead we did the work for hundreds.
I'm certainly no millionaire but I have as a Bitcoiner opened up my circle of successful people by saying yes, to helping others and in return they've helped me with resources when I needed them.
So when Doctors, Lawyers and Plumbers cry about people doing their work it's because they have not helped enough people themselves and they have to con customers into getting jobs. Instead they should help people to learn how to do things and they will be able to get help when their skill set is insufficient.
