But I believe there is a reasonable point at which people should not be expected to go beyond because it becomes ultimately too harmful for them (ok... maybe that's not our business) and society which has to deal with the fallout (very much our business). Its why we have labor laws. Laws on how long truck drivers can drive without sleeping. People shouldn't have to degenerate into selling their souls and risking the well being of others for short term survival. Society shouldn't degenerate to competition at this kind of level. It really shouldn't.
I do strongly believe in the individual's right to chose. But as with all ideologies, purity generally produces very sucky real world outcomes and a modicum of sense and nuance has to be applied for the thing to work. The powerful shouldn't be able to lay traps for the less informed and then stand back and say "oh well... they chose...they have to accept the consequences while I reap the benefits". That's not how civilization should work.
Are you also opposed to those medians and guardrails on highways that impinge on your freedom to drive off the road when you so choose?
For example, since you bring up roads -- narrower lanes make safer drivers: http://www.planetizen.com/node/80229/another-study-shows-nar...
That's a statement born out of extreme privilege. For substantial proportions of people, there is very little freedom involved: You take what is on offer, or you lose your house or don't eat. One side has an extreme amount of extra leverage, and some of them takes according advantage.
People died fighting for the 8 hour working day because without regulation employers simply did not give a shit if they were working people into an early grave. We have May Day labour demonstrations in large part of the world in part as a result of what is now the AFL-CIO wanting to commemorate the Chicago Haymarket massacre, and restart what was already then, in 1880's, a multiple decades long fight for human working hours.
In other instances, people burned to death because of employers that thought it ok to lock the factory doors to prevent workers from taking unauthorised breaks.
Is that an indication of a free exchange?
For a free exchange, both sides need to have reasonably equal power.
I would love to hear your thoughts. I'm hopeful that both classical and progressive liberals can find common ground in a basic income. Combined, we are an unstoppable force for human freedom and prosperity.
The temptation is strong to ban other people from making different trade-offs than us, because it keeps them from besting us in competition and challenging our value systems. But what right do we have to dictate what other people should value and what trade-offs they're allowed to make with their own lives? My sweat, blood, and tears are mine and mine alone to give and withhold.
