"Joe's porchbuilding" does not send automated greetings. They want a website that is discoverable on Google by new clients and can display their pitch, everything else is negotiated on phone or by email anyway. You only need to worry about security issues if you build such a site on top of a dynamic platform. The updates and security issues disappear if you serve factually static content as static content.
Static site generators are bad for dynamic websites, but that does not mean you have to try and fit a whole dynamic platform into a static website. Different use cases, different tools.
