Well, no, there's also the choice of making PKIs work -- that requires
more political work than technical, and may be as infeasible as a good
unregulated PKI has been.

Also, I'm not sure that well-regulated PKI will necessarily be a good
thing -- I can already imagine the complaints about how red tape slows
everything down, doesn't scale, blah, blah, blah.  But if the consensus
here was that that is what we need, and if politicians told us it's
feasible then it'd be worth trying.

How long has the consensus been that web security is broke?  Admitting
you have a problem is the first step, but it is not sufficient.
