I'm for fighting the government tooth an nail when it comes to more regulating of anything. I'm all for letting stupid people be there selves.
As for inbreeding, never a good thing. An calling it line breeding changes nothing. Everything achieved by inbreeding can be done by out crossing. It just takes a little longer an costs more. Inbreeding is used because its ether cheaper or its quicker or both.
My opinion, every time you bring a new generation of females in to breeding you should have a new male from another line. Sure it costs more an your not as likely to have litters full of grand champions but you are more likely to have litters that die of old age.
I dont show my dogs. I breed for health not looks. You cant do both. One has to take priority.
