Just a few points here.
1) "Company towns" are an issue with monopolies and "pure" capitalism... something Mises himself (basically the economic forefather of the Austrian school and most Libertarian economic theories) accepts, especially in areas with natural resources (such as a coal or mining town). That said, it's not as if all company towns were an unmitigated evil; many were leading examples of progressive town planning which actually improved the conditions of the workers there. Even the infamous Pullman town enabled its workers to have a higher standard of living than they would have otherwise expected.
2) On the healthcare debate itself I fully understand that the Obamacare "compulsory insurance" is far from a popular option on any side of the debate. That said my admiration for the Swiss system
(which also requires compulsory health insurance) is near boundless. It may not be completely Libertarian because of Government interference but for a major economy it's pretty close... and it does well at all attempts to rank it. The WHO rankings last published in 2000 rated it 20th in the world (above the likes of Sweden, Germany, Finland and Canada). I also think the system used in Singapore
is worth a look... another system that fuses public and private but with most of the emphasis on private.
3) With regards to regulations it's worth noting that the market came up with a solution to that (at least with regards to consumer goods). Branding. People bought brands rather than whatever else was on offer because brands were a guarantee of a certain level of quality (both of safety and the good itself) and that lasts to this day; people buy goods because of the strength of the brand (albeit one aided by marketing) and if a brand doesn't live up to those expectations it normally fails as the consumers moved to something else. Look at Coke's attempts to sell bottled water in the UK with Dasani. In the space of about 2 weeks it fell apart (and barely a month after it was launched)... first it was revealed that it was just tap water (a common occurrence in bottled water products but not one you want advertised), then it was revealed the "highly sophisticated purification process", based on Nasa spacecraft technology, was in fact reverse osmosis used in many modest domestic water purification units and then finally it was discovered that in trying to change the "taste profile" they were pumping oxide into it, turning the bromide (contained in the calcium carbonate they previously pumped into it) which turned the non-harmful bromide into the cancer causing bromate. The brand never recovered and was quickly withdrawn... and was never launched across the rest of Continental Europe. It's also a solid example of how a strong brand can help... a lesser company could have been completely destroyed by that (or at least in the UK) but because of Coke's strong reputation for its other products is survived.
