Open terminal, select text, copy. Doesn't sound too difficult

Oh my... Duh! Of course you need network, because how else will the phone download the terminal and other developer tools??

99% of users will never enable developer mode, therefore it would be pointless to have all these tools preinstalled (which would mean all of that would have to be updated with each system update). Just a friendly reminder - you need network for downloading Media Player, Calculator, Clock, Mail, Calendar, ... as well.

Of course, I forgot, having network on a phone is something very peculiar these days
