It is absolutely incorrect to state that all baptized persons have the right to the sacraments. First, no one in fact really has the “right” to divine grace; within the Church as an institution and as a perfect society, however, those who possess legislative authority can declare that Catholics have a juridical right to the spiritual goods of the Church. These rights come with obligations, of course, one of which is to be united to the Church. To be a Catholic in communion with the Church (in the external forum), one must accept the entire faith, the sacraments, and the ecclesiastical governance of the Church.
In general, baptized persons have the right to the sacraments if they 1) ask for it at an appropriate time, 2) are properly disposed, and 3) are not prohibited by law from receiving them.
For a baptized non-Catholic who refuses to convert, but who desires Catholic sacraments, he is likely not “properly disposed”. This is not a judgement on the state of his soul. “Ecclesia de occultis non iudicat”, and so whether a person is properly disposed is a judgement the minister must make in the external forum. If a non-Catholic wants to receive a Catholic sacrament—which signifies unity with the Catholic Church—but is not willing to fulfill all three conditions to be in communion with the Church, how likely is it for him to be properly disposed?
In addition, generally speaking, baptized non-Catholics are in fact prohibited by law from receiving Catholic sacraments. Canon 844.1 lays out the general rule: Catholic ministers administer the sacraments licitly to Catholics, who likewise receive sacraments licitly from Catholic ministers. The subsequent paragraphs of same canon provides exceptions, that is true, but exceptions are subject to strict interpretation (c. 18).
