I don’t have a lot of experience related to this so I’m just noting some things.
Some people in this thread don’t seem to think it’s that hard or overcomplicated.
When reading Designing Data-Intensive Applications my main takeaway was that event sourcing can make it easier to solve a lot of issues like performance, scaling, consistency, auditability, etc.
It would be interesting to look into what a low overhead way of implementing CRUD with event sourcing in Postgres would look like, then decide if it’s too complex.
Try making Hackernews lite. Users can post, comment on posts, vote/unvote posts, and delete their own posts and comments. CRUD tables might be post, comment, maybe vote. Event tables might be create_post, delete_post, create_comment, delete_comment, vote, unvote.

Don't trust anyone who tells you event sourcing is simple to implement.
