There's no `/usr/local/Brew` (or whatever directory it uses) either, but it creates it, and it changes the ownership of `/usr/local/bin` to make it writable without a sudo prompt - which is more egregious than creating a `~/bin` directory, any day of the week. If they didn't insist on using `/usr/local/bin` (which is in the default $PATH) the permissions issue would be much less of an issue IMO (not a non-issue, but less of an issue than it is currently)
