Hiding coin amo= unts would make it impossible to audit the blockchain and verify that there= hasn't been inflation and the emission schedule is on schedule. It would i= nherently remove unconditional soundness from bitcoin and replace it with c= omputational soundness. Even if bitcoin did adopt it, it would keep backwar= ds compatibility with old style addresses which could continue to use ordin= als. Nit: it isn't technically correct to say that amount hiding "inherently rem= oves unconditional soundness". Such commitments can be either perfectly hid= ing or perfectly binding; it isn't even logically possible for them to be b= oth, sadly. But we are not forced to choose perfect binding; El Gamal commi= tments, for example, are perfectly binding but only computationally hiding.
