Actually there is one such living practice amongst Jains, https://en.wikipedia.org/wiki/Santhara https://en.wikipedia.org/wiki/Santhara sAkyamuni himself did, and many sAdhus today go to great trouble to become "asaktaH" (non-attached). It's said that former recognized the errors in this path, gave up on this course, and attained nirvana the subsequent day. Unless this is modern propaganda, I imagine Kobo Daishi was aware of it too. India too has not suffered a loss of creatures who file PILs at the slightest deviation from the fashionable. (note: Jainism is a traditionally recognised nAstika school, one that's not grounded in the vedAni. By this definition, Buddhism too is Hinduism - the demarcation only became rigid in the past ~200 years.).
