That’s for a fine-tune of an existing SD model that has already trained on a mountain of data. Training from scratch requires a mountain of image data and a lot more compute, so you would need a 100% clean base model as well, but then yes it’s totally doable.

There are a couple existing pretrained SD models that use all CC0/public domain data. I think at this point they're still significantly lower quality than other popular models, but I'm sure that will improve over time.
