You're Absolutely Right...in a wrong kind of way (Score 1)

The final medium means nothing if any of the recording, editing, mixing and/or final mastering are done in the digital domain. Dynamic range compression is typically applied during several stages during the production process. First - on the way into the recorder (whether it is analog tape or a DAW), then during mixing on individual tracks and across the final 2-buss master (master buss compression). Then it's usually compressed and/or limited again by the mastering engineer as they create the final 2-track master.

So, how does vinyl prevent any of this?? It doesn't!

The only change will be that once the final master is made - it will need to be limited an additional time to control the cutting head to be sure it doesn't break through the groove during the cutting of the master vinyl disc. This may bring the overall level down - but there is no change to the damage already done by having 45 minutes of music with a total of 1dBspl of dynamic range. The issue isn't just that the recordings are too loud - it's that they remove the natural dynamics to get the loudness, causing listening fatigue nearly instantly.

Sounds like someone needs to take themselves to an audio engineering class to figure out what exactly happens at all these stages and where the problem really is.
