On top of that, an autism diagnosis rarely gets you any support that isn’t Applied Behavioral Analysis therapy. That’s essentially dog training for your autist (designed by the same B. F. Skinner of “Skinner box” fame using the same principals), and people who have been through it have described it as torture. The ADA doesn’t make many accommodations for folks with non-physical disabilities, and cops have no idea how to interact with folks with communication barriers and an inability to control their bodily movements. It’s tough being autistic in public. It’s tough trying to navigate our society as a parent of autistic people. With or without insurance, it’s hard. The problems are not purely financial.
I recommend some books on the subject, particularly Neurotribes by Steve Silberman and Unmasking Autism by Dr. Devon Price.
