Whenever I have to do a fresh install of Ubuntu, the first thing I do, before even updating to new packages, is remove programs I don't need or use (Bluetooth, gwibber, empathy, etc.). This doesn't take too much time, but it is fairly annoying and I worry that I don't also remove all the different bits and pieces of each program even after apt-get autoremove.
Why do I have to install these programs in the first place?

Seems like you have questions about how package management works. I encourage you to ask those questions in the forums.
There are two anserws to your question 'Why do I have to install these programs in the first place?'
1) You don't. The question indicates you have outgrown the limitations of the LiveCD, which is intended for new users to try Ubuntu. Advanced users should use more advanced and flexible tools. The minimal installer, the alternate installer, and other install methods do already let you safely customize your install. They also tend to be faster and download much less. Try them.
2) The specific reasons that the LiveCD is all-or-nothing: First, the LiveCD is intended for new users. New users won't know what to choose, so it's quite rude to ask them a lot of questions they won't know the answer to. Second, the same new users expect the installed system to be just like the live system they tried, again without pestering them with unanswerable questions.
