Serious answer since you seem to genuinely not know, several possible reasons.

- Bare metal performs better.
- Linux generally performs better than OSX, this can have small or large impact in the host layer depending on what hypervisor and guest configuration is used, but it is non-zero. What hypervisor ships with OSX, by the way? How does it compare with KVM?
- Virtualization has some administration overhead. There are some benefits of it as well, but if you wanted those and wanted to minimize "tinkering", then you would use Linux on Linux/KVM, OSX is a new thing you have to work with.
- OS debugging and performance work is easier without a hypervisor, and much easier with a hypervisor you know and can easily modify if required.

Probably others, but this is enough that someone like Linus who knows Linux very well and doesn't want to tinker with proprietary software would avoid Linux in a VM on OSX.
