It being natural doesn't mean anything, though. Plenty of naturally dangerous things out there...

Webauthn isn't just for 2FA, it's for user user authentication through public key cryptography. Passkeys are Webauthn, but the former is a better marketable term.
Repetition is how people learn to remember things and improve their skills. I fail to see how that's bad.
I hope you know what you're doing. That's a good way to share company secrets with outsiders, also it's uncertain whether you're even legally allowed to use the resulting code.
No problem. One more tip though: If you ever censor your public IP, don't just censor the last two digits. Otherwise it will be easily brute-forced.
My preferred option is to have the VPS inside a VPC that blocks all external traffic by default. Then I can open up specific ports for specific IP ranges.
The reason I prefer this over a firewall configuration on the VPS itself is that the latter seems far more error-prone to me. For example, I've had problems in the past with ufw and Docker where container ports were still reachable even though access was denied via ufw.
Yeah, microplastics seem to be overlooked too often when people talk about plastic recycling "solutions". The worst one I've ever seen was a video where they cut a plastic bottle into strands and then made a broom out of them...
Let them eat cake
If an attacker already has access to a system, they can use hitherto closed ports to communicate with C2 servers or attack other devices. In that case, a firewall that only allows known-good traffic will prevent further damage.
And thus the enshittification cycle completes
I don't doubt it, I just have a problem with the reasoning that something is "natural" and therefore good. It's a common misconception that charlatans use to prey on people.
