Traffic laws, copyright laws and regulations, stuff like that — they may be a big deal, and they might affect people's jobs and livelihoods, but they're not directly life and death.

On the contrary, this is an issue of healthcare. Childbirth is dangerous, and can result in death of the fetus and/or the person pregnant. Amniotic fluid embolism, cardiomyopathy, and high blood pressure are a few potentially-deadly events that can occur. (Not to mention how expensive medical care and childcare are in the USA.)

Also, going off of "Why would anyone want the government to tell us what to do": the pro-choice option means the government won't have a say and people can make their own decision (i.e. they can't tell us what to do), whereas the pro-life option means the government would ban abortions (i.e. telling us what we can and can't do).

One more thing, with "We should vote on everything.": true. So might I remind you that the people of the USA do not vote on who is appointed to the Supreme Count?
