Earlier quoted context omitted.
Write your signature. Scan it in. Apply it to documents that want signatures. To some people, this doesn't "feel right" the same way that it doesn't "feel right" that I have rolling star-base office chairs around my dining room table. They are far more comfortable than any "dining room chair" I've ever been in. In both cases, when people don't take my good advice, I shrug and move on.
Ok sure so use a pen or use the printer to write your signature - that doesn't change the need sometimes to go give the doctor/school/solicitor/etc a physical copy . You can keep your "good" advice, but please do move on.
I also have a printer for those rare occasions. More commonly, I copy-paste my signature image onto the digital form and send it right back.
