> I would count myself among those who would prefer to have working phone service again without endless junk calls

False choice. It's quite possible that this will not substantially reduce much less eliminate the junk calls.

It will substantially reduce my ability to obtain an anonymized number that no one knows about and has any reason to junk call. I don't get any junk calls on my anonymous numbers, if if I did, I'd toss that number and get another and the junk could not follow it unless whomever I was using the number with was the source of the leak and then I'd stop doing business with them in the future.

Past privacy violations are what are driving the scam calls, making their be a mandatory loss of privacy at the moment you get the number will not help.
