Except the problem is that you can't really back up Google documents. The file format is closed. You can, of course, periodically export them into common document formats. But you can't restore the same Google document and expect it back with all its functionality.

For the rest, you're completely right. Everything possible should've been backed up. It just has nagged me that a real backup isn't possible, and it has bitten me in the past (corrupted drawing, which corrupted related documents as well). Since then, I have only used the Google sheets/documents/etc. for throwaways and drafts.

There are multiple third party services which use the API to make daily copies of your documents, exporting them as MS Office documents. Yes, this isn't perfect, and you can lose some info in the files, it is pretty good for the most part. Nobody shpould be using G Suite without this, IMHO, because this happens too often.

I'm paranoid and tell people to print out data they can't backup and put it in a safe. I've always had some essential data printed out put in a fireproof safe :-) But yes Google is bad at this.

If you have critical data that can cost your company that you can't backup, your're living a risky life. Hopefully they've checked with their colleagues that those agree with living that risky life.
