All your arguments are correct, but are unrelated to the main motivations for ORMs. ORMs are about: - Convenience of using SQL from $LANGUAGE where mapping the result, (re)naming, etc. is handled for you. Do this manually, and eventually you will either make silly mistakes or create your own mini-framework. - Connection pooling / retrying if desired. Can be done without, but again mini-framework. - Migrations. Generating a schema from code is neat. - Making our lives miserable when the ORM inevitably generates horrible SQL somewhere and we need to override it manually. That is, ORMs are NOT a replacement for learning SQL.
