You fail to see freedom in relative terms, there are natural limits to "freedom" some are limits in the interest of an evolving society such as quotas and affirmaitive action - they are temporary but serve to right a wrong over time and alter the makeup and attitudes of a society. Some limits to freedom are in the direct interest to society such as forbidding false advertising, enforcing ingredient labels, demanding full disclosure.
What you are looking for is a sort of freedom that is not possible in a modern society. If I manufacture and sell a medication that has no effectiveness and could easily be taken rather than a legitimate medicine to the detriment of the purchaser, is that violence? If I and another person enter freely into a contract where I say that this sterile sea water will cure your cancer but only if you do not undergo traditional chemo therapy - has violence been done to the cancer victim? (that is a true story btw - my friend died as a result).
You presume certain things exist that do not, can not or will not.
