With regard to making birth control OTC, that doesn't solve anything in this case. Looking only at the four methods here, an IUD obviously can't be installed over the counter, and buying one off insurance costs $500-900 or so.
Plan B can be bought OTC, but costs something like $50 for a one-time pill. That can be reduced if you can get to a Planned Parenthood or similar, but those reductions are designed to work alongside insurance, not replace it.
The other drug, ella, is prescription only but can be bought online from automated prescription services for ~$60. Again, discounts are sometimes available, but again these work best alongside insurance.
Given the goal of the two pills is to reduce the risk of a pregnancy after high-risk sex (condom broke, etc) reducing the cost is a valid goal. Especially for low income women.
Regarding the buffer zone decision,
SCOTUSblog's plain English summary. It's a bit of a complicated ruling. They did find that buffer zones at abortion clinics are legal, but that;
...the law does restrict more speech than it needs to. No other state uses a buffer zone like this one, which suggests that there are alternatives that Massachusetts has overlooked. First and foremost, if the goal is to protect patients and more broadly maintain order outside clinics (which, the Court agreed, is a legitimate interest), there is a separate provision of the law that specifically addresses misconduct outside clinics and imposes criminal penalties for violations. Or the state could enact other laws to deal with it. Either option would allow the state to target particular individuals who block access to clinics or harass women, without penalizing people like the plaintiffs who say that they are just trying to talk to women. The Court also expressed skepticism that access to and public safety around clinics are actually problems anywhere other than one specific clinic: “For a problem shown to arise only once a week in one city at one clinic, creating 35-foot buffer zones at every clinic across” the state “is hardly a narrowly tailored solution.”
Nor, the Court continued, can the state justify the restrictions by saying that it tried other options but they didn’t work; the five Justices pointedly observed that they saw no sign that the state had tried to rely on those other options to prosecute anyone in the last seventeen years. And even if the fixed buffer zone was easier for police than some of the other options, the Court was unmoved: “[T]he prime objective of the First Amendment is not efficiency.”
Again, a strict scrutiny ruling based on the fact that there seems to be a more narrowly tailored or less restrictive manner of achieving the stated goals.
One thing I would note here is the group claiming they just want to talk to women (as opposed to groups who go to court for the right to explicitly harass them?) are
'sidewalk counselors' whose goal is to talk women out of having abortions on the way in.
