Since the id() function isn't documented as returning an address, I'm not sure
why you think that it is significant that Python programs can't discern such a

You could equally interpret it as:

- the IQ of the person reading the output;
- the number of legs on the average insect;
- the number of times per day the average teenager says "I don't even";
- the number of days in a month;
- the amount of memory in terabytes required to store that object;
- the number of atoms of hydrogen in Moscow; or
- cost in US dollars in lost productivity caused by this discussion

whether it's useful or not to interpret it that way. You are free to interpret
it as anything you like, whether or not it is useful is up to you.
