That is to be expected, not everyone will like it. Especially in abstract theory. I have a lot of the same qualms. But I don't think it will have the effect you mention and if it does it will be something reconsidered.
Ultimately though, if one person doesn't' want to talk to the other, but the other can follow them around and harass them it is not a very good community and has it's own very significant downsides.
Most decisions like this come with tradeoffs. Yes, if people can block others it will mean they can choose to have a more insular experience that questions their views less, but it also means they can avoid harassment and abuse more easily.
In my study of this kind of feature's effect on a community I do not see the outcome you envision, but if there are historic cases of this I'd love to have a look at them.
Edit: a better way to answer this is to say that your concerns are valid more on the individual level than the community level. If you go around blocking people it will mean you have a more restrictive experience, a little bubble so to speak. But it doesn't mean anyone else has that experience. It doesn't really change the whole community's experience the same way, one person can't block someone for everyone. In fact the increased ability to shape their own experience means there is less need for that kind of thing (typically a community ban for all people).
