Why is it so important to get pot legalized? (Please read details).

One of the most common things I hear about the legalization of pot is that “it’s just stupid that it’s illegal.” I do agree with this but, this can be said about many laws. Why is it so much more important that pot be legalized than, say, it be legal for a 16-year-old and 15-year-old to have sex? At least, in the state of CT. It is illegal in the US to drink if you are under the age of 21. Many people find that stupid but still, people are much less vocal about this than legalizing pot. It is illegal in the state of CT and a few other states, though I cannot remember which ones to carry a civilian grade stun-gun. This seems like a pretty stupid law to me, and if it were legal to do so, it could actually save lives.

My point is not to start another pot legalization debate, nor is it to have my examples of laws picked apart I realize two of my three examples are specifically state laws. My point is to understand why people are so much more interested in legalizing pot than legalizing other things that also hurt no one and that could benefit the country the US from their legalization.
