Why i dont use github (or any version control)

Id love to have my mind changed on this, but I personally dont see any place for github or other version control for the types of sites that I make and maintain.

Im a bit of a version control newbie but I do use it at my job, where I do mainly front end coding. I use drupal for freelance projects that I do outside of work. I use a fair few contributed modules but I dont create my own modules or write extensive php or javascript. As most of my changes are therefore in the database I cant really use the diff feature of version control.

I also dont make sites with any hardcoded links. With the pathologic module, when I move my site all I have to do with flush the cache and all the paths update to what they should be. This means I can duplicate the site's files and database (changing the database name) and keep working on the new one, leaving the old one as a backup. I find this is a good way to make backups as they are working sites. So if I run into an issue down the line I can 'go back in time' and see if this problem always existed or if it was caused more recently and so must be due to a change ive made.

As might be obvious my freelancing projects are pretty small scale so the budgets mean that I need a quick and easy workflow. Am I missing a trick here? I do have a slight phobia of using the command line which im sure isnt shared by proper developers (im more of a themer). Thanks
