One way to get closer to this goal is to buy an liberated X200 or similar machine, which can run on only free software, install a free software OS like Trisquel and only ever install free software on it. Buying such a laptop from people in the free software community will also support them and their work. There are a few shops. On the web you will still need to deal with how everything these days is behind the currently hip and trendy CDN, but you can choose not to use such websites. You can have a main machine and your freedom respecting machine. You choose your own compromise. I did that some time ago and I have to say I love my freedom respecting mostly distraction free X200 for writing or coding. It is a great machine to work with, if you can accept old hardware and the implied worse performance.
