Maybe. But often people don't look at the TCO. You are going to need to scale that database up and down, regularly do backups and then test those backups, integrate and manage monitoring, ensure it is highly available across different data centres, ensure you are testing new releases/patches and then managing the upgrades e.g with canary releases etc. Or you can just use the DaaS and get all of that for free as well as 24/7 support when something bad happens.
