I'm no expert in JSON, but don't you lose the ability to filter it before your application receives it all? If you had a reasonable amount of data then in SQL you can add WHERE clause and cut down what you get back so you could end up processing a lot less data than in your JSON example, even with the duplicated top table data. Plus if you're sensible you can ensure you're not bringing back more fields than you need.
In a traditional SQL database, yeah. In various document-oriented (NoSQL) databases, though, you can do that.
Modern relational databases have support for it too including indexes etc. For example postgres.
Every major SQL database supports json manipulation nowadays. I know MariaDB and MySQL and SQLite at least support it natively.
