I enjoyed David Friedman's discussions of the incentives present under market anarchy in "The Machinery of Freedom", now available in its entirety online[1]. Your objections are not new and have been discussed at length by market anarchists. Whether or not you find the responses satisfactory is up to you.
David writes for a mainstream audience which is assumed to have some familiarity with concepts of economics and property, but does not need to already be a libertarian. I feel he is the best representative of market anarchist thought.
One thing I don't get with libertarianism is why this, second paragraph of the book, doesn't apply both ways:
"People who wish to live in a 'virtuous' society, surrounded by others who share their ideas of virtue, would be free to set up their own communities and to contract with each other so as to prevent the 'sinful' from buying or renting within them. Those who wished to live communally could set up their own communes. But nobody would have a right to force his way of life upon his neighbor."
