Let me outline an alternative situation where an individual would have no freedom of choice, but where you might agree with the measures imposed. Suppose we identify the first case of Ebola in the US next year. Do you support forcibly quarantining that person? Such an action is eminently necessary in my opinion. But at the same time, such an action violates the two things you've laid out: (1) it doesn't allow the individual any freedom of choice, (2) it is not guaranteed that they'll spread it and is therefore restricting their freedoms merely on the probability of aggression.
