The slight more complex reason is that working in the big wide world involves stresses and difficulties that are particular to your faith.
I was consulting for a large FX trading firm last summer and working in their office for three days per week for four weeks. There was a 40 year old married woman and a sodomite male work colleague who were clearly the closest of friends as well as work colleagues on the desk island closest to where I had been provided a workstation. Their 9 to 5 banter consisted of graphic descriptions of what they got up to last weekend, or what they would each like to do to the same male celebrity or bitching about the fashion sense of the latest female celebrity.
Now I am pretty thick skinned and I have spent a career working in offices, but this really went beyond the call of duty. You just have to cope with it and offer it up.
If you now add to that naturally occurring problem the rigourist layer of additional rules that some Rad Trads then introduce about trousers are evil, talking to married women in an office inappropriate, socialising with colleagues after work an occasion of sin, usury is evil, using LinkedIn and Facebook is evil and a sign of a compromise with liberalism etc, etc, etc, etc, then just about every job opportunity and EVERY career path is shut down to them.
Thus the desire to be organic farmers, hermits, teachers at Trad schools, pundits or somehow be supported by the cult they hang around with.
