It would be difficult to go to community college if one is disowned. Also, if the student does stay at home, s/he will have to endure more parental abuse, and the whole issue of college/major arguments will continue anyway (including in selection of four year college/major to transfer to).
Going to a full ride merit scholarship college may be a more feasable way to escape from a tiger parent who is willing to refuse to fund college or disown the kid.
