Here is an idea. Just the threat of filing a complaint with:
The Enforcement Branch of the California Department of Insurance headed by:
Mission: "To protect the public from economic loss and distress by actively investigating, arresting, and referring, for prosecution or other adjudication, those who commit insurance fraud and other violations of law; to reduce the overall incidence of insurance fraud and consumer abuse through anti-fraud outreach and training to the public, private, and governmental sectors."
This could even force the eager cooperation of management at flying sites (Parks) to aid
any non member (or barred member) of the USHPA in acquiring insurance coverage.

or, The Fraud Division Overview:

may be two good places to start.
What is Insurance Fraud?
"Fraud occurs when someone knowingly lies to obtain a benefit or advantage to which they are not otherwise entitled or someone knowingly denies a benefit that is due and to which someone is entitled. According to the law, the crime of insurance fraud can be prosecuted when:
The suspect had the intent to defraud. Insurance fraud is a "specific" intent crime. This means a prosecutor must prove that the person involved knowingly committed an act to defraud.
An act is completed. Simply making a misrepresentation (written or oral) to an insurer with knowledge that is untrue is sufficient.
The act and intent must come together. One without the other is not a crime.
Actual loss is not needed as long as the suspect has committed an act and had the intent to commit the crime. No money necessarily has to be lost by a victim."

Having had first hand information about a person being denied insurance coverage in the State of Minnesota a formal complaint wasn't even necessary. The Insurance Commissioner somehow found out that I was being excluded from insurance coverage and the SIU arrived at my house on their own.
Apparently they were interested in exactly who was standing in the way of me purchasing insurance.
