Why not? You're the one who said people should be spending their time doing innovation in biology, hacking on deep learning, and starting a blog, rather than learning how to configure and deal with networking. If anyone wants to do those things, they can do them now and not have to worry about installing and configuring servers and dealing with IP networking. Or they can work on innovating in networking. The fact is, however, that no one is going to say "if my server wasn't IPv6 only, then people would read my blog". They'll most likely be saying that because there's a lot of other content to consume on the Internet, and attention is limited. And if that is the case, they can get a $5 a month digital ocean instance, or one from any number of other providers, accessible over IPv4 and IPv6, and serve both protocols to entire Internet. Also, chances are, the audience for a physics student's blog is most likely at some university, which has a good chance of having a working IPv6 stack; especially now that MIT is going wholehog on IPv6.
