inalienable rights. They are CHANGES that were made to the constitution. And the Bill of Rights are just the first 10 amendments that were ratified (there were two other amendments that didn't get ratified at that time).
Prohibition is an amendment to the constitution(the 18th) which was repealed by another amendment (the 21st). As you stated, drinking alcohol is NOT an inalienable right. I read those state laws that you posted, but none of them say anything about the Bill of Rights. They speak of inalienable rights, which the constitution says is "life, liberty and the pursuit of happiness".
The original question you raised was "what happens if a change to the constitution directly contradicts another?". The answer to that is that the Supreme Court would determine which of those contradictory laws should be followed.
The part that seems to be getting bogged down is that the Bill of Rights is NOT a list of inalienable rights. It is a list of Government granted rights that may or may not alienable. I would argue that the right to Free Speech SHOULD be an inalienable right, but it isn't necessarily. You might argue that the right to own a gun is inalienable, but it also is subject to the interpretation of a government body. As you also stated, you cannot yell "Fire" in a crowded theater, which means that there are times when your right to Free Speech can indeed be taken away.
The constitution talked about Liberty, but it was agreed at the time that this was an inalienable right if you were BORN free (which was pretty much not what was practiced, since so many Africans were born free in Africa, then kidnapped to be enslaved here). The Supreme Court upheld this law in the Dred Scott case. So, it can be seen here that what is considered inalienable is completely up to the government to decide. I agree that the government shouldn't have the authority to "take away a right", but they do it all the time.
I guess the issue is: What do you consider to be an unalienable right (and just saying "all of the bill of rights" is cheating. Is it just the Bill of Rights? Are all the amendments inalienable?)? What you and I come up with might be completely different, but what matters is what the LAW states is an inalienable right.

Edited to add: Thanks for correcting the number of states. I couldn't remember if it was 2/3s or 3/4ths and was too lazy to look it up.
