Evidently you have your own thoughts on this, so it's pointless me bantering away - but why can't and why shouldn't I make my choice my default?
If I set up the stylesheet to have an order of preference, with a fallback to default system fonts that mangle my considered layout, then you're perfectly free to do what you will - but again (and we're going around in circles here) - it's my content, I'd rather like to display it as I wish.
Look, I'll be honest - there are times and situations where I wish there were still properly text based browsers that could read web content (assuming it's been marked up well enough in the first place) and display it in green-glowing monospaced terminal text - but there aren't. The world's moved on - I'm sorry you don't like it.
