A TCP session is a unique combination of client IP, client port, server IP, and server port.
So you can use the same IP and port as long as the destination is a different IP or port.
This means that in principle you could use the same IP and port to connect to every IP address on the Internet using 65536 concurrent sessions. 😆
This wouldn’t help going to popular destinations, since they have a lot of people going to the same IP address and port, but for many (most?) of them you probably have some sort of CDN servers in your data centers anyway.
For people saying “it’s fine”, they are probably not talking about the same thing
I assume you mean this monstrosity:

Which is indeed a crime against humanity. My parents used one and kept me from realizing that coffee is delicious until I was 18 years old or so.
The other people probably mean this simple yet effective device:

Especially the comment about 60 million Italians.
The moka pot is great and I use it to make my own latte every day.
