A good sized readable font is a bit funny though. That line of text is very small on my phone and I presume most people today browse on phones. I can also imagine some phones with a higher resolution show this text even smaller making it completely illegible.
I'm all about minimalism so long as it doesn't hurt UX but these examples of minimalism always end up going too far. It's like it becomes a competition for minimalists - "look how much more minimal I am than you! Therefore I'm a better minimalist."
