The benefit is standardization. If every team you join has a `docker-compose.yml` to run a local development environment you know exactly what it is, how to add things to it, etc. If every team you join has a custom solution for an extremely lightweight development environment than you need to be brought up to speed every single time.

It's a similar argument to "Why do you need Makefiles when you can just write a bunch of bash files and a meta-bash file to execute each sub script based on the stat results of a list of files?"
