Sure there is. The law allows you to refuse that inalienable right for yourself. The law defines food and water as "medical treatment". Maybe the laws should be clarified - if the law doesn't allow you to refuse medical treatment, and the law doesn't define food as "medicine", then we don't have this problem.
Secondly, your bit about the Governor 'driving a hummer into the lobby' or whatever is a lying strawman, meant to create an impression that has nothing to do with reality.
LOL. Shall I dredge up some posts where folks were wishing for essentially that, that Jeb and the National Guard would storm in, that W and the FBI would storm in, that Bo Gritz and his merry militia-ites would storm in? LOL. No, it's no strawman - it's been offered as a serious suggestion here. Not by you, that I've observed, but it's certainly been on the table.
A nurse with an order from the Governor could have rescued Terri.
A judge with a bill from the legislature could have saved Terri. Why did no legislative body step up to provide one? Not in Florida, not in Washington, nowhere. They say it's not their fault they sat on their hands, and you're ready to believe them. Don't.
Terri's family's lawyers should have invoked the Americans With Disabilities Act. As the disability rights group Not Dead Yet has pointed out, she was deprived food and water simply because of her disability.
