yes? you can legally purchase a plane without a license… did you read my comment? purchasing != using. You don’t need a pilot “under current contract” you could buy a plane and taxi it around the airport if you want without any licenses.
You can, you just need to hire a pilot if you want to fly in it. How do you think rich people fly around in their jets? Do you really think the pilots own the planes?
If you are looking for FOSS, I highly recommend joplin. It’s simple but works well. I used it for many years until recently I switched to Obsidian. I dislike that Obsidian isn’t FOSS but I’m using the free tier and the community plugins really make it so much more powerful than Joplin. They both store things in Markdown so I’m not locked down to their ecosystem which I think is a requirement for any note taking app.
I just think as someone new (like the OP), setting up vanilla pihole is a little easier.
Not all I self-host but pihole, plex, & homeassistant are certainly my most used.
Same with firefox
