It does, but it also limits the damage. If you lose your DNSSEC key,
bad guys can forge names below you in the DNS tree. If you lose your
CA key, bad guys can forge any name they want.
Or to look at it another way, if I put effort into securing my own
DNS, and I am careful about the providers above me in the tree, I can
limit the chance of DNSSEC compromise. With SSL, it doesn't matter
what I do, I'm always at the mercy of the next Diginotar.
