I dont know what you guys are all upset about.
Right now, in California and in most other states it is absolutely LEGAL for a high school dropout with zero medical training to own and operate a medical clinic. Now, can they prescribe medicines or do surgery? Of course not, but all they have to do is hire a doctor to do so. Shocking, I know.
Take a look at all the urgent care clinics, MinuteClinics, TakeCare, etc. Do you think physicians own those practices? Think again. They are owned and operated by corporate structures with boards and CEOs who have zero medical experience.
Given that is the case, you guys have no reason to have special protection for PT practices. You are very lucky that "only" physicians are being granted ownership privileges, given that California is very prone to letting anybody own or run anything else in terms of healthcare. Be glad that they arent allowing athletic trainers own PT shops, YET.
