The whole strength of our faith is in mesorah, the faithful transmission of the Torah from Rebbi to talmid. Otherwise, anyone can make up anything they want and ch”V make a mockery of the Torah.
Now, if you want to take a different Rebbi with an equally valid mesorah from his Rebbi then that is one thing. But to invent your own new mesorah is quite another thing.
That is clearly not historically true. Sometimes circumstances called for new outlooks on things. Otherwise I will wait for your threads decrying Chassidus along with Zionism.
