Neat idea and I wish you luck but a few issues are going to make it nearly impossible to be anything more than a well intentioned idea that never flies:
- Unions require unity which there is zero of in the fiercely independant and competitive world of porn
- Too much time and expense to launch with out a decent bank roll to get it going - no one will buy into something that doesn't have an office, employees, a business plan, etc.
- FSC could feasibly take this on but has not, even though they were intimating something along those lines a while back... why did it go nowhere?
- Dues would have to be low enough that performers could afford it on their sporadic incomes but that would hinder maintaining operations until the volume of people supported it but then how long do people stay in the biz for it to make sense regardless?
- Historically, similar efforts have failed - mainly due to apathy
- Unlike mainstream, "indies" rather than "studios" provide most of the paid employment opportunities
- Needs to offer more than just testing verification to really justify payment of dues and good luck convincing anyone that holding their money in trust until retirement is ok
I could go on but you get the drift...
