This is a chicken and egg argument.

Both of these arguments rest on the assumption that RCS replaces iMessage. That's not the point. The data is already unencrypted. You already need a paid phone number. The benefit is that two large groups of users' devices that interact poorly today interact better with RCS. Google isn't asking Whatsapp or Signal to implement RCS, it doesn't make sense that they'd expect Apple to shut down their proprietary service to use a less-featurefull option instead.

How is Adoption a chicken and egg argument? RCS is, by its design, slower to update than iMessage.

Because iOS has a large enough market share that carriers don't prioritize adoption ("It doesn't benefit our customers"), but a lack of adoption means Apple can say "Why would we waste our time on something that's not well supported?"
