You are going off at a tangent. The mechanism for preventing the phone
number being obtainable from a query of the phone book or directory
enquiry services is not relevant; just the fact that it can easily be
done.
Consider these scenarios:-
1. I have a phone number that you don't know.
This phone number is listed in the phone book and at directory
enquiries.
It is trivial for you to obtain the number.
2. I have a phone number that you don't know.
This phone number is not listed in the phone book or at
directory enquiries.
It is harder for you to obtain the number.
A parallel exists with:-
3. I have email addresses that you don't know.
These email addresses are readable from my key's user IDs.
It is trivial for you to obtain these email addresses.
4. I have email addresses that you don't know.
These email addresses are not readable from my key's user IDs.
It is harder for you to obtain these email addresses.
"This phone number is not listed in the phone book or at directory
enquiries" is easily achieved by being ex-directory; this does not
affect the usefulness of my telephone service. It is only easy because
the appropriate mechanism has been put in place to achieve it.
"These email addresses are not readable from my key's user IDs" is
easily achieved by simply not including them in the user IDs. This is
easy because the user ID field is free-text and doesn't have to be
Name (Comment) <email address>. This adversely affects the usefulness
of my key, since MUAs commonly rely on the email address in the user
ID for key selection.
Hashed user IDs are a possible alternative mechanism to achieve "these
email addresses are not readable from my key's user IDs" that could
have less of an adverse affect on key usefulness.

I said "in this respect the two are similar."
You appear to be saying "they are not similar because in these
other respects they are different."

A good point well made.
I was comparing the effort involved in actually creating a new email
address (a few seconds to a couple of minutes at the keyboard) to the
effort involved in actually getting the phone company to change a
phone number (ringing the phone company, navigating their stupid menu
system, eventually getting through to a customer service agent in
foreign parts who barely speaks English, trying to make them
understand, discussing the reasons why they should provide the number
change - such as nuisance phone calls you have been receiving, wait
for the change to happen, chase up the billing errors, etc.).
