If the world did not exist outside your echo chamber, then it wouldn't be a problem. The problem with echo chambers is they trend away from information and knowledge and toward whatever is most often repeated. Add some malicious disinformation providers to the chamber, and like a capitalist monopoly you find yourself in a much worse situation down the road. Replying to your specific items: 1. Indeed, and this can limit our opportunities and make our lives worse. A very simple example is land management. Still in some parts of the world it is common to pour things into the soil or water which are harmful to the environment... the environment that the same people live in. Sooner or later this results in harm for the people living there. But their echo chamber, so to speak, knows that the way to dispose of something you no longer want is to throw it into the lake or canal.

Also, is "athiest influencer" a thing!? This expression of "echo chamber" is probably more recent in human history because we now are able to easily travel outside our original bubble, and of course because we have the internet. You didn't know you were in a bubble when neither you nor anyone you knew had ever been out of the bubble. One could argue that school is bad because it teaches things that we don't need... because "obviously" anything we need could be taught to us by our parents or village leaders. See #1.
