Oh geez, one's a bit... restrictive, ain't it?
Screw the rules, I'm going in with a list.
1. I'd probably remove most self-destructive prohibitions. Now, I do not like drugs, and I usually don't get along well with drug users, it's just me, I have a very big personal value of sobriety, tend to dislike most forms of hedonism, and it gets applied to most cases. But... I have to agree that self destruction is the choice of the user. Same as bicycle helmets, fireworks, etc. Let it be, let the herd thin out, I'm sorry, but our species needs it. I know it must suck to be someone who has these kinds of accidents or habits, and maybe they're not really stupid or anything, but... I'm sorry, the world was never very nice about such things.
2. Legalize lethal injections. I mostly mean this for prisoners, specifically for ones serving life sentences. I know that they're not always 100% proven guilty, but I imagine a fair amount are pretty damn set, and there's no reason to let their life drag on like that. Yeah, it's more of a punishment to let them live, but... jeez, I don't think we should do something just for the schadenfreude of it. I think this could also apply for people with terminal illnesses, or in an incurable vegetative state, with some form of consensus from the family. This one would need a really strong definition to be an actual law, though.
3. I agree whole heartedly about the parenting license. See, in this area, there was a woman who kept getting pregnant, but she was not in the mental condition to be raising a child, and the government kept having to put them up for adoption, she didn't even want them anyways. Eventually, the doctors actually... I think they tied her tubes, I don't know. There was a huge legal fit thrown, and I don't know if that can be undone, but something got done about it. Interesting enough, a mentally challenged couple also had a kid around here, and they were raising it rather well last I heard. See, it's a really hard thing to determine, and the conditions might be hard to define, but... there are some people that are just going to raise detrimental kids, or they'll die young, or something else bad will happen, just because of this or that reason. It... I think the rights of the child should come before the rights of the parents. We should be offering protection to those who need it most.
4. Now, I think here in Canada I could beat a man within an inch of his life for entering my home, dunno, never tested it, but if that's not allowed in other places, I'm against it. I think you have full right to punish someone for entering your domain without permission. Bar killing them, or permanently disabling them, maybe, you should have full right to break out the gun, or bat, and get a little bit confrontational. I'm pretty sure a shot in the kneecap heels eventually.
And... maybe I'll edit if I come up with things. I'm not really for prostitution, so I don't want to say that. I can understand the desire to tax it, and that if done right, it doesn't do much damage, but... sex is another thing I can get high and mighty about, but I won't here.
EDIT:
5. I'm pretty sure gay people can get married here in Nova Scotia, but I certainly would like it to be a universal thing. I feel that the churches should have some say on whom they allow, I understand that it's a big thing for them, and besides, you can get married in other places. I never wanted to get married in a church anyways, I always thought a park would be really nice.
But yeah, more as I think of them I suppose.
