The font size problem is not always solved by an increase in font size. The problem (sometimes) is that when a smaller font size is used, it's too small. So when you increase the font size so those sizes are no longer too small, other font sizes can be too large. I do agree to let the base font size be the default and adjust the others from there. But don't go stupid and go too small or too large. I've not seen too many eBooks with too large. But a lot do have too small.

I do sometimes read on my phone and when I see things like a 14% white space for a chapter header and a 10% left/right margin to do a simulated blockquote, I just think stupid designers. The screen sizes used to read with are not the same. They range in many different sizes. My way to look at eBooks is to take the smallest screen you think people might be using and design so the eBooks look good on that and also check if they look good on a larger screen. My idea of the smallest screen would be that of an iPhone 4s.
