If you're working on projects of a certain scale, it becomes a legal issue. If it's personal site you're talking about, or a small client, then practically I could agree. But there's no reason to ignore accessibility guidelines if you're aware of them. I like to use tab navigation since sometimes it's faster than a mouse. But if you make your button a div, and don't add tabIndex="0" to that div, I can't do that. Your comment is too presumptuous about how people actually use computers.
