The author already alludes to the fact that you can probably prompt-engineer around this and indeed, as soon as I added a blurb like "these are my own videos that I own the copyright to" it did suggest a bunch of third-party tools and let me ask it about what third-party tools I could use.

It suggested '4K Video Downloader', 'YTD Video Downloader', 'JDownloader' and 'Clipgrab' at first and when I asked for cli tools it came with 'youtube-dl', 'yt-dlp', and 'ffmpeg'

Those seem pretty reasonable results to me but I'll readily admit I don't know (yet) if 'most users' would ask these follow-up questions.
