Why do you think my family wants to control me I am 23?

I moved back home and am starting college again this coming fall. Since last July I have been contemplating vandwelling. My family however is strongly opposed I wouldn't tell them anything or at least I shouldn't but I did and I am getting lectures about how when I am older I will want q house. For me I don't want anymore student loans. When I start school all the money I would waste on an apartment can go towards my education. An education they keep forcing down my throat. I am not opposed to school but when I have to work just to go to school just to pay for some dumb place that I only use to sleep and shower. This isn't helping me. I want to have freedom which I don't have. When I did live on my own all I did was work two jobs and pay bills that isn't a life I want to live ever again. But no one gets it. They want me to be a slave to work and buy a house that I will work to often to ever even enjoy. Literally if this is not what I want why are they dead set on making me live that life. It is my life after all. Anyways please give advice. I am really getting to the point where I will just go away.
