For the first decade or so of caller ID it pretty much told the truth. Businesses sent their number or withheld it entirely. Most countries have legislation requiring businesses to have some level of visibility - publishing address or registration info etc. Since the growth of robodiallers and sales scams faked CLID has become almost the default. It got so bad that I simply no longer answer calls that aren't in my contacts. They've ruined the phone system. As for anonymity, I'm imagine most who would approve of it for individuals would not think it sensible for a business. Why would I trust or give money to a business that wants to be anonymous and lie about themselves? So yeah, I'd like unfakeable CLID and to get back to a working phone system.
