For me, it’s not enough to verify the integrity of an ISO – I also have to verify its authenticity (or at least verify the checksum file) with GPG. I don’t know why, but just need to see that “Good signature” message before I feel safe installing Linux.
I notice, though, that the download pages of some prominent distros (Pop_OS!, openSUSE, etc) just give you a checksum, probably because they feel that anything else is unnecessary. This makes me shy away from installing them, which is a shame because I’d like to give some of those distros a try on bare metal.
Am I being paranoid when it comes to installing Linux?
Someone could’ve compromised the materials used to build the CPU, better assemble the atoms together one by one.

Someone could have hidden something malicious within your ideas, better create a whole new conceptual system.
