I might be misreading your comment so that being said:
If you wear a body cam because you feel threatened, hopefully you tell others that you're potentially recording them. The other catch is that the smart glasses do more than simply record video such as facial recognition and so on. Often these are things that have privacy ramifications that neither the wearer or the observer know exactly.
Do you misunderstand the risks or just accept them personally?
The issue is usually that you are imposing the risks onto others without consent. I did not sign the terms and conditions of your cloud providers data collection.
You can be recorded in public, it is not a forgone conclusion that everyone can be run through data capture systems without their consent, society is still working through that. We can still decide on a more fair outcome.
