If you think prostitution and drug legalization are the cornerstone of 'freedom', you totally disregard common logic.
Non-initiation of force or fraud is the cornerstone of "fredom", and this includes initiating force or fraud against those who sell their body, or ingest substances you disagree with.
You may want to shy away from using the word "common logic". You may as well say, "..you totally disregard my personal views".
That's a big 'if'. I see one's life decisions made of voluntary consent and the lack of fraud and coercion as the cornerstones of freedom. What people choose to do with their lives is their own business, not mine. If they choose poorly, it is still their choice so long as they don't harm me. That is freedom, and it is entirely logical.
That's like asserting that machine politics and vote buying are the cornerstone of 'democracy'.
Not cornerstones, but acid tests. Try substituting 'contract rights' and 'unlicensed medical practice' if those two bother you.
Are you FOR the right of two people to contract anything they please?
Are you FOR the right to hire anyone, without qualification, to give you medical, legal or other - advice, treatment or services?
You are upset not based on the principles, but on two ramifications of those principles that you would rather exempt from your definition of 'freedom'.
