MongoDB is not the same as Postgres and jsonb. also, I'd challenge your thinking - ultimately the goal is to solve problems. you don't necessarily need SQL, or relations for that matter. that being said, naively modeling your stuff in mongodb (or other things like dynamodb) will cause you severe pain... what's also true, which people forget, is naively modeling your stuff with a relational database will also cause you pain. as they sometimes say, normalize until it hurts, and then denormalize to scale and make it work the amount of places I've seen that skip the second part and have extremely normalized databases makes me cringe. it's like people think joins are free...
