When you have a small number of systems, a small team (possibly one person) and a relatively simple configuration it can be hard to justify spending time and money on a lot of deployment and automation. It isn't that deploying systems as you suggest isn't a better way of doing things. It is just the benefits are far greater at scale. At the scale I typically work it would be over-engineering most of the time.
