You may have plenty of resources but there are many that have to "make due" with 8 GB, 4 GB or even less RAM.
Totally fair, but I think the Venn diagram of folks that use Docker and folks that have 4GB of RAM is pretty slim. If the resources are that limited, Docker might not be the best choice for running anything.

Again, not advocating Chrome in a container, I don’t even run Chrome outside of a container. I just think it’s odd to get hung up on these sorts of resource requirements given the state of computing.
