Is it normal that my father refuses to accept that i am mature?

So early on in my life, my parents apparently ripped up my social security card and never decided to get a new one for me.
They never told me my social security number because they don't remember it. Now this is very important as all of you know to have in life and the fact that my parents (especially my dad) blames this on me is just idiotic.

Now, earlier today I asked my dad if he would teach me how to use a gun properly... He said I wasn't mature enough, although he has been saying that since I was 12 years old... I am now almost 18 and he's still saying that.
I have my own business and earn my own money from what I love to do. I have worked on my health for the past 3 years as I have been incapable of doing much because of a disease I had gotten that made it physically impossible to go to school. Although, I pushed as hard as I could and worked on getting better every single day for 3 years of my life. During those 3 years I was homeschooled and sure I didn't get the best grades but that was literally because of the job I had and still did and the stress of getting back up on my feet to actually be normal again.

Out of all this hard work, my father still doesn't recognize that I am a mature person. Apparently in his eyes, only school can prove whether someone is mature or not. Now like I said, I wasn't getting the best grades, but even when I was in school I was still getting C's. This is mainly because my father literally yelled at me every night of my life for many years. Even when I was bed ridden with a physically disabling disease he yelled at me till I got a job which was extremely hard for me to do because of the fact my parents refuse to allow me to get my drivers license.

I have to be driven there and whenever I asked, it's always the same answer "We'll go on so and so day" and when that day comes, they never take me. School starts in less than a week and I'll have that which is far more important than anything else to think about. Whether it be driving or not. I am really unsure of how to get out of my parents life because they make it physically impossible to leave.
I know how to drive a car, they just won't let me get my license. And unfortunately I need 2 forms of ID... which I don't have because I don't have my social security number and only my school ID... that's it. My parents won't give me a second form of ID because they know if I had one, I'd go out and get my own license and move out. I really don't think it's normal for parents to be this mean to me and I am unsure as to what steps I need to take to get my life going without them knowing, But I need some sort of other opinions on this because I really don't know where else to go... IIN?
