The good news is that none of the successful lead web developers I have worked with meet these requirements. I feel like you're talking about a large team more than a single developer, and in many places where you say "expert," I would say "willing and able to tackle the subject to the extent required."
I think a better way to sum up web development, instead of making it sound like an impossible job, is to say there is virtually unlimited scope to make yourself better and more valuable at the job by expanding your technical skills.
