All of these are legitimate issues with AV software. However, they don't mean that AV is a crutch, or that it could easily be supplanted by other security features. There is simply no good alternative to AV for systems where it's likely the user will interact with untrusted input, such as receiving documents, receiving email, browsing the internet, downloading code from GitHub etc Of course, when you have a locked down system such as a server or an embedded device, the need for AV protection drops down significantly. But on a wide open system, there's really no alternative.
