That's kind of important to the story though.
Sometimes that can be fun, but only if everyone at the table is onboard for a wild tangent. If the other players are bored as shit while the special snowflake starts a unicorn breeding operation, it's time to use that No. And you, the DM, are included in that too; if your players want to drag you off to write every book in the library and that's not fun for you, you have the right to say "hey maybe you should play the game I made for you instead."
Addendum to the "Are you sure you want to do that" bullet: if a player ever does something that seems nonsensical to you, ask them what they expect to achieve by doing that. Understanding their motivation is often what resolves the miscommunication and/or allows you to steer them towards a better way to do what they're trying to do.
There are a couple ways to get auto-generated transcripts from youtube (eg https://www.howtogeek.com/793947/how-to-get-the-transcript-of-a-youtube-video/ ), but there are enough errors and bad UI that I find reading them to be more miserable than just watching the video.
Looking good! Those pirates have a pretty sweet setup!
