So, sure. We haven't been able to do individual-level blocking, so let's add a

Heh, appreciate the humor. It certainly won't make it work worse.
A reasonable view, I think, but it occurs to me that it could. Taking a
narrow, precise requirement -- even one we don't know how to satisfy --
can be made harder to satisfy by confusing the heck out, where an
additional requirement creates a distraction.
This might move a "we don't know how to do it now, but might be able to
figure it out" to a "we don't know how to do it now and almost certainly
never will"...
My point if you will, is that requirements are more complex than what's stated.
The reason we won't get them fulfilled—simple or complex—is because there is no
incentive for the bad guys to follow the rules.
As noted earlier in the thread, there are some actors who are not
criminally inclined. Ignorant and/or aggressive, but willing to follow
the rules, or at least mostly. So, for example, they properly identify
themselves. And given a sufficiently forceful requirement, they will
grudgingly conform.
The other view expressed in the thread was that such folk are not
currently an interesting problem, but the criminally inclined are. (I
think aggressive legitimate companies /do/ warrant some effort, but it
needs to be reasonably limited and efficient effort. That's what we
don't yet have.)
IIRC, there is (was?) a "National Do Not Call List" implemented in the US at
the federal level. Telemarketers and other organizations are required by law to scrub
their own lists against this federal registry. This has not made a dent in the amount of
spam calls that I get on my various lines.
Telephone-level DNC is a different category of technological
requirement. Very different.
