No, that's not at all what he's saying. He's saying that intellectual property is actually an immensely broad and complicated issue. (Rather: That's what I interpreted him to be saying; I could be wrong here.)
I don't think you can really make a statement like "IP laws lead to slower development of science and industry..." because "IP laws" are such a broad category of laws. Do you mean patents? What kind of patents? (Does a 5 year patent on medicines, something proposed by the Pirate Party, count as an IP law that reduces development? Why? How does it differ from other patents that are longer / renewable?) Can I make a contract to stop someone from disclosing an idea of mine? Is that an IP law? (Probably) Is it aggregating money into the hands of the few? (More dubious claim there...)
Don't get me wrong, I tend to agree that there should be limits on the sorts of monopolies that IP laws tend to foster, and I think that the current IP regimes that are dominant are typically very damaging. But I also think there could be certain IP controls that are acceptable and positive. (Allowing for IP regimes that are basically "trade secrets only" seems a bit inadequate to me, especially since patents offer valuable protections to certain kinds of innovations.) This is a view that your wildly over-broad/under-specified interpretation of IP would not accommodate.
