This is a crazy argument - When governments consume anywhere between 30 and 60% of the GDP of a nation, OF COURSE they are going to be involved in markets. This is not proof of anything other than the existence of big governments.
And no one disputes that government research labs can produce new technologies and breakthroughs. Of course they can. The question is whether they are uniquely capable of this, or whether the free market would engage in research and development without government funding or direction. Simply stating the existence of big government programs is not an argument against libertarianism.
There’s another logical problem here, which is that it’s easy to make a case for government when you only consider the benefits and ignore the costs. In the other thread, some of us have provided evidence that government R&D actually displaces private R&D (i.e. private R&D spending has gone up when government R&D spending goes down), and the same pattern exists for charity.
There is one obvious case for government R&D, and I’m surprised none of you have bothered to make it - R&D that is very expensive, and for which no known market exists. The Large Hadron Collider, the Cassini Orbiter, Hubble, etc. There is much dissention among libertarians regarding this type of R&D - some would say, “hey, if people don’t want to pay for it voluntarily, tough noogies.” I’m a little less libertarian that others in this regard, and I think there is room for government-funded R&D in basic research where it’s clear that no market-based solution exists.
The notion that the internet would not exist today without government just does not pass the smell test. In this case, there was clearly an increasing market demand for online services - they were was already a burgeoning market in it and big money was being invested. There’s nothing magical about TCP/IP - it’s just one protocol out of thousands. Had government never bothered with distributed networking at all, we’d still have an internet today - it would look different, and we don’t know if it would be better or worse.
You could even make the case that government slowed down the growth of the public internet, because it created a network that was made available to government institutions and educational facilities, lowering market demand for such a network, and then dragged its feet on making it available to commercial interests. That created a parallel private communications industry - CompuServe, AOL, The Well, thousands of BBS’s, modem companies like Hayes and US Robotics, etc. We’ll never know where that industry might have taken us had those government networks not existed, because you can’t know the path not taken.
The larger point made in the other thread though is that the initial backbones and protocols are not what ‘the internet’ is today. The real internet is the vast collection of web sites and services that have built up organically without any government direction at all. The internet today is largely the result of spontaneous order caused by a free market, not government planning. It is an example of a libertarian virtual society. Anyone can set up a web site. The barriers to economic engagement on the internet are very low. There is no government oversight ‘protecting’ internet users from each other. There’s just a whole lot of voluntary transactions.
As for the market consolidating around large companies and becoming monopolistic - first of all, not all Libertarians oppose anti-trust laws. Second, this effect is grossly over-stated in most cases. IBM didn’t lose its power because of anti-trust - it lost it because it didn’t anticipate the micro-computer and minicomputer markets and bet the farm on the IBM 360, only do see its market share get eaten by companies like DEC and Data General and Honeywell and others, and then later by Apple and other small computer manufacturers.
Libertarians would also argue that the best examples of monopolistic power come from companies colluding with government, or from the government itself.
