Is it weird with the current technology that someone who claims....

Not necessarily. I have a sole proprietor business that I operate from home that provides services to others outside my home. I do not advertise or have a website as I am a one person business. My clientele is generally based on word of mouth from my clients. I choose which jobs I want to do, some of which I do turn down. The only technology I use is a computer spreadsheet to track my earnings, my company earnings and company expenses. I have no need for a website or any other social media to promote my business.
