This game clearly takes place in the U.S. so how about we use that as the baseline. And yes, it's impossible in the U.S.
That's been discussed.
In the US Maya wouldn't have a problem. She doesn't need a co-signer for a loan because the government is the co-signer. If her Dad took a loan for her college then she just needs to drop out, the bank will claw back the loan when it's not used for tuition, Maya has no debt for life, her Father has no leverage on her. Then Maya can take out a government loan and continue her education and her life.
It's been pointed out repeatedly that there is no loan problem. Maybe Maya is just really stupid and doesn't realize it. So then she can find out, with just a little effort. How?
She could google it on her phone. If she can't afford internet for her phone she could go to the library and look it up, or use one of their computers.
She could ask any teacher.
She could ask her girlfriend, who is a Business Major and in any sane, competently written universe, would surely know.
I wrote all that out just to show that it is impossible for Maya's Father to force her to stop dating someone with the threat of withholding any help with her college cost in any real world scenario. And no, her Father's church isn't going to loan her the money, in the US that's regulated. If that was the case she just has to walk away, she can't be held liable for the debt. If a church or any other organization is giving her money for college it's a scholarship, and that doesn't have to be repaid.
So we can't use the realworld situation as a baseline. Maya lives in Duckburg and the rules of the universe are different there.
So where does that leave us?
It leave's us with Maya, a pathetic, useless character who is perpetually in need of a savior. If you want to be Maya's savior go to it, enjoy yourself. But not everyone wants that, even though we are forced to endure it, Maya just won't go away and let other people enjoy the rest of the game.
