That's definitely part of the problem, and would inhibit laws since the publishers know they'd get the free money. Perhaps the government could also regulate the publishers and say they can't charge any more for open access than they can for subscription fees? Or, perhaps the different agencies can create their own journals for their funded projects and let the research appear in them? Basically, create new reputable journals precisely for open access? Or make it where a paper has to be submitted to a "prestigious" one and an open access one a year or so later (i.e. author keeps copyright, period), which would hopefully build up the prestige of them? I'm not sure the solution, just trying to think of ideas.
