You can’t erase an amendment. But the Bill of Rights is not a collection of Amendments; it is a statement of eternal unalterable foundation facts without which the Constitution goes away.

I've always viewed the Bill of Rights as Jefferson's "unalienable rights" written out in more detail. Plus, it was made a part of the Constitution prior to ratification by the States (at the States' insistence), so any attempt to "amend" away part of it could be seen as an attempt to vitiate the Constitution in its entirety.
