Which is the same as PostgreSQL [1] or SQLite [2] that can store JSON values in binary formats (both called JSONB) but when you "SELECT" it you get standard JSON.
They both store JSON, each in some particular way, but they don't both store it in the same way. Just like they both store tabular data, but not in the same way, and therefore get different performance characteristics.
Are you arguing that since Clickhouse is a database like Postgres, there's no point for CH to exist as we already have Postgres? Column-oriented databases have their uses.

Wow, that escalated quickly. You are reading too much into my comment. You should read the comment thread from the beginning to understand which question I'm replying to.
