Well, I am not sure about your point. I support people's right to ride a motorcycle without a helmet, but I don't ride a motorcycle anymore. I support people's rights to go rock climbing without ropes, but I never did that myself.
Homeschoolers like you may be pioneers, but don't be so dismissive of "supporters". There are not enough of you to get anything done in this political system without the at least tacit support of the rest of us. Do you really think that the few pro-homeschooling laws passed in some states are solely the result of the activities of the homeschoolers themselves? Do you think the legislatures would have given a Rat's a$$ if there were not supportive, but non-homeschooling parents who also supported homeschooling?
Besides, you weighed the pluses and minuses and decided that the plus of homeschooling (good teaching, perhaps God-centered education, less crime, etc.) outweighed the minuses (you knew in advance your kids could not participate in the stuff at the government school).
