Yeah, most (all) of these arguments seem silly. The primary argument not to use it in emails because someone MIGHT improperly quote your email in a reply and then NOT encrypt their response? Well someone might screenshot your Signal app, or have malware on their phone, or a million other things. It seems like such an absurd corner case to me.

For my use case I don't have any concerns about using GPG. I encrypt files with it, and if anyone wants to put up any money that they can access my files, let me know what escrow service you want to use.
