But nothing can stop spoofing of phone numbers as long as FCC regs do
not mandate fixing to source.

What if phone companies could recognize numbers that don't belong to
anyone's phone and change the caller ID to 000-000-0000, or some other
number that everyone could block?

And change the NAME to "Junk Caller".

Where are you (or they) going to get a complete list of all phone
numbers that are currently assigned to a person (and not some entity
that makes calls for a multitude of callers)? Hell, you can't even get
info on who owns an existing (assigned) cell phone number. Those online
lookup services are crap that require you to pay to get more details
than a huge regional location or with what telephony provider the number
originates.

What the phone companies could do is not what they have done. They have
no financial incentive to employ all the hardware and software for a
feature that is yet to be pervasively requested by their customers.
Simultaneous ring has been available at some providers for over a couple
decades, but those that don't have it now are not likely to add it.

The telephone companies were actually constrained by the FCC to complete
all calls. Didn't matter if they knew or didn't know if the caller was
a spammer or scammer. They were required by law to complete the call.
The telcos had their hands tied. Only lately has the FCC given them an
out where they can block some calls. Because this is a very new change
(November 2017), it will take time for the telcos to decide what, if
anything, they will do. Since there will be hardware and software costs
involved, they may add an anti-spam call blocking service but they can
also charge for it. How many customers are going to up the cost of
their phone bill by even $5 to get service-side anti-spam call blocking?
