You're not wrong. What you are missing is how much complicated web development (and software development in general has become). Even if you are doing a simple Static website it's more complicated than yesterday. If you are using Git to push your changes, you already need to push to Github and then SSH into your machine, make a pull request. Oups. Now Nginx is still serving the old version through cache. So need to clear cache, restart, shut this, reconfigure this, etc... After a while this gets tiring. Docker is not the perfect solution (one can wonder if it's actually a solution) but it's a symptom of the real issue rather than the issue itself.
