Even then, the system is opt-out. Anyone can become a renunciate who are beyond caste.
Can you give me a source for this? I've never heard of anyone renouncing their caste, and I have heard about many instances of lower-caste people lying about their caste, and I can't reconcile the two.
Beyond caste might be misleading. You can always become casteless, but that is worse than being the lowest caste.
