macOS and iOS is completely useless together

This is probably going to be an ongoing rant about the integration of MacOS, iOS, and modern communications. I left a drinking establishment perhaps 3 hours ago and seem to have left my iPhone 6S there. As of 1:19PST, I can track my device on the "Find My" app on Catalina but can't send messages to it. My 5 year old iPhone is somewhere in the Tenderloin. Impressive that I can track it, but the tracking app offers no options to send messages to it. WHY? In the process, I also discovered that I am completely without the ability to contact any friends or family without my now lost iPhone. I can't make any text messages or outbound calls from my shiny 16in macbook pro (with its ridiculously sized trackpad and marginal keyboard). Whatsapp requires having your phone as the central device to even be able to use it, which is of course no fucking use when your phone is gone. I don't have a landline in my house, as I suspect most people don't these days. In San Francisco. I can literally see minute by minute where my phone is in the Tenderloin but have no way send a message to the device, to my friends, or to my family. How in the hell is this where we are at in the the 21st century?
