I agree, but only when 'as it is' means absent the hard-fork needed to induce unhealthy growth which will drive the solution under control of centralized and almost certainly corporate interests.

Even at the current broadly supportable transaction rates there is still a very significant looming threat of non-fungibility attacks (aka 'tainting' and associated 'bitcoin license' requirements.)  Whether defenses against such attacks could be effective with the realistic possibility of massive decentralization of support infrastructure, I do not know.  I'm certain that it will be all over for Bitcoin if/when such attacks are mounted if by that time Bitcoin is significantly popularized and centralized though.
