I would argue with his proposition that SSTO is infeasible with current technology. Even winged is possible, with aerial refueling.

I would also argue with his criticism of materials. Every space vehicle I've worked on in recent years has been at least partially composite. With the right designs and materials, even composite LOX tanks are feasible. And the structural material isn't the issue when talking about reentry. When you are talking about reentry temperatures, comparing carbon composite and aluminum is like comparing styrofoam and cardboard when you toss it in a furnace. Other materials take care of thermal protection.

I think he badly underestimates Rutan on issues like fatigue and maintenance.

He makes a good point that a cheap orbital ballistic vehicle will have a greater impact on space flight than a suborbital spaceplane. But there's room for both in the marketplace.

I think the engineers out there have a pretty good handle on things. He's worrying too much.
