If we use the analogy of physical stationery and forms, each one serves a specific, tailor made purpose. A tax form, daily journal form, double entry accounting form, an invoice, etc. are specifically designed for that purpose. You could technically use a blank page as a starting point to make any kind of form you need, but straight up blank pages are not very efficient outside of personal home use. Notion and its brethen, AirTable, etc. are just pain in the ass to set up. They're infinitely customizeable and that's a bug, not a feature IMO. I'll take a proper CRM or a Wiki tool over a blank slate.
