I may have stripped it out. Given the ease with which a client can be installed ("sudo apt-get install ...") then why waste the space. Sure it's small but the principle stands, and many small programs add to lots of space - also that small program is going to be downloaded millions of times unnecessarily, written to CD/DVD, written to HDD or flash drives .. countless transfers and writes, even for a few KB that's a waste.
I'm sure the popularity-contest data shows that FTP is used quite a lot. Gopher barely ever. So, "no" unless there were a "command line tools" checkbox on install that could be used to exclude it. I've never actually used the FF ftp (until you mentioned it) and didn't even know it was there - I only occasionally use ftp in a console, usually I'll use Dolphin or Krusader (KDE4).
You have a standard domain name (as siblings note) and run a gopher server via that name. You'll have to have your own server (or virtual server) as I can't really imagine any hosting company allows gopher servers?!

Edit: first it's poor links2 support, now no linkifying of gopher links, shocking ...
