Guiding Thunder has been described as a form of barrier from its debut. Before we had a proper databook name, the next best thing was something Shikaku said, calling it a "jikukan kekkai", and even its databook entry uses the term.

Keep your fingers in your ears Lorenzo. Even people alive at the same time build upon other people's jutsu. Kakashi taught Sasuke the Chidori, and during the timeskip Sasuke made many improvements through further shape transformation. You're trying to have your cake and eat it too. In one post you attribute time use for the improvement of Edo Tensei with Orochimaru and Kabuto, and the next you claim time use doesn't matter for FTG with Minato.
