Umm, I think because Liberty is apart from freedom. I don't find duckduckgo, as a 'go to' for my comprehension, but almost a 'try' at conveying your thoughts. Perhaps a little more work towards life experience, and knowing what it entails would be up to par?.

Freedom, is as I wrote in the OP, but without a lot more in your tool box, you won't know how to exercise your 'freedom' towards your betterment; hence Liberty; let the light in bro.
