Why do women agree to hookups and then ghost you?

Not once have I ever had a girl agree to hookup with me and then follow through. I've sexted girls, traded nudes, agreed a time and a place but every time, they end up ghosting me, or cancel on me multiple times before blocking me. Recently I even had a girl agree on a time and a day. We sent/traded nudes and everything. She even sent me her address (which I still have). Then the next day she cancelled on me saying she had a job interview. I told her that's fine and to let me know when she's available and that if she has any second thoughts to just let me know. She said "Don't worry, I'll let you know if I do." Then the next day I went to message her and saw that I was blocked. Girls? Why do you do this? I don't understand the point.
