This is only an issue if there is some centralized platform (ie Meta) that hosts AR and has a monopoly over the space. It's actually likely that that will happen (the average user won't be using the niche platforms) and that everyone will have a "space" with some sort of control over whose you can see (very similar to social media like twitter)
