Paper doesn’t have kedusha. The words printed on it have kedusha, which is why a siddur goes into genizah.

Just because our forefathers did something doesn’t make it right. Eicha says that our forefathers were idol worshipers, which is true. To say that something becomes holy only because klal yisrael does it, not because it is commanded by the Torah, is not Orthodox. It is, however, exactly what Mordechai Kaplan wrote about. Claiming that minhag yisrael is inherently holy, especially when it contravenes halakha, makes one a Reconstructionist, and pasul.
