Is there a point of applying to a University if potential adviser rejected me
You may have answered your own question in the comment above, I fear.

In many disciplines, as you say, 


  a department will not offer acceptance if there is no one to supervise you


In those disciplines, offers tend to me made only if a particular faculty member advocates for a student. If the faculty member you would like to work with is not taking students, it seems unlikely that you would be admitted. So if yours is one of those disciplines, save your money.

For further discussion, see this question.
