Except that you have to know exactly what <program> is, character for character, and usually includes some long string of numbers and letters where 1 character is wrong and you have to retype the whole damn thing. This is the opposite of easy.

If it a program you are unfamiliar with, yes you’ll probably need to search for the apt name and copy paste. I much prefer that over searching a website, verifying it’s not a scam site, then download the exe, and then run the exe once the download is finished. After the first time, just add it to a .sh script and then you can download every program you need automatically if you ever need to set up a new instance again.

I guess it’s not for all, but worst case it’s hardly any more work than needing to go to a website to download the exe.
