This all sounds good, in "we're all adults here" sort of way, but instead of nodding I found myself troubled.
1. If "practicing safe sex" and "check in and let me know you're alive" are okay, why isn't any other rule or restriction? Those are both about your and your partner's safety, and about your peace of mind, so allowing that and outlawing other things that are also about safety and peace of mind just seems like hairsplitting.
2. Sure, if you're inclined that way. If not, then restrictions and rules can be as playful and fun as a good pair of leather restraints.
3. Oh, but they are. Partners A1 and A2 agree on a set of rules. A2 conveys those rules to B1, who has the option to agree or disagree. That's eminently fair. That's leaving aside the issue that restrictions and rules aren't necessarily about control. Sometimes they are, sometimes they aren't.
4. There I agree, at least in theory, but I can see a situation where one or the other takes a possibly irrational dislike of someone. I can live with that, possibly with a head-patting "sure, sure, of course I won't have sex with that awful man" nudge and wink, but it's not a particularly onerous restriction, because there are a nearly infinite number of people who won't push that button.
I think every relationship has rules and restrictions and negotiated settlements, some implicit, some explicit. If it feels like control, that's either because it is - in which case a lot of talking and some therapy is probably a good idea - or because you don't understand that a relationship is an entity with its own requirements and those can supercede those of the individual. It's an issue of common good, I think.
Your paraphrased quote is another place where I take issue. It doesn't really hold up. The thing is that most of us are somewhere between good and bad, mostly because we all walk around with our inner toddler still alive inside of us. It's fine to let it out to play, but it still has to have a bedtime and a routine.
