I DO NOT think you are an idiot-- I commend your research and introspection. Welcome, and please do not take this the wrong way!
The thing is, they will also leave (your roommates)...your bird could bond with them (not you, or you--but you don't know, as sexual maturity changes everything, even for a bonded baby)..Plus, being "a hippie animal lover" doesn't mean you will always think about things like the harmful impacts of essential oils , or even soy candles..or the fact the teflon is al over space heaters, air fryers, popcorn poppers, toaster ovens, hair straighteners, blowdryers etc.....or the serious importance of routine /sleep spaces and the result of broken bonds when parrots' favorite people leave "the flock".
I would recommend that you wait until you are independent and living in a house before moving forward, but I think you are commendable for your research etc....plus, there are cats...a single/minor scratch can kill them due to the bacteria that they carry. Not saying you cannot have a cat and a cockatoo, but it is another risk---and with multiple people in the house, it only takes one to leave the wrong door open etc.
It's can be very hard to control multiple adults in a home, even if they have good intentions.
