Companies like OpenEye scientific publish many papers and proudly (for whatever reason) declare they have never received a government grant for their research.
When you work in an industry full of people with PhDs, lots of papers get published that didn't receive government funding; people with PhDs like to write papers.
though I have a similar desire I don't think that's a good argument for justifying it. why? evaluate the following symmetrical situations:
> I paid for the [tank, aircraft carrier, nukes, Fort Knox, etc] with my tax payer money. Therefore...
that said, I do think there's a greater net benefit to humanity, and scientific progress will accelerate, the easier, cheaper and less restrictive access we have to papers and research results.
That's not a very good comparison, as those are all rival goods, and furthermore have obvious negative externalities (IE are dangerous). I can't think of a non-rival government-funded good (without harmful externalities) that would NOT make sense to to make freely available.
Edit: Oh hey, I'm being downvoted for an opinion. Sitting at -1 right now.
There's a far better comparison to be made with IP produced by NASA, for instance, which is automatically released directly to the public domain on the grounds that the American public is who commissioned it in the first place (for the rest of the world, it's a gift - you're welcome).

edit: Most of the biggest high profile publications from NASA get published in Science/Nature, which are both closed access FWIW.
