I would assume it's because of memory issues (human ones, not SQL ones)--for instance, if I have a 60-column table that I want to add a single column to, what are the chances I'm going to retype all those column names and definitions correctly? Not so much of an issue these days with all the automated tools available to help with this, of course, but SQL as a language came into existence 40 years ago and it definitely would have been more of an issue back then!
Not if you're used VCS, which was around early.
This has never been a problem for me because we have generally put structure changes to databases in scripts which we retain for configuration control purposes, and which can contain comments.
