I think it's actually the other way around, satellites need to be specifically designed to burn up fast in the atmosphere. See for example the warnings about space debris from Chinese satellites not designed with this in mind.

There is some evidence to suggest that spacex knows how to reenter an object without burning it up.

The engineering overlap between between a small object designed for reentry and a flying (crashing...) warehouse is not a circle.

Once upon a time there was a bonkers "rods from god" mass bomb idea, but that didn't work either.

Sometimes without even meaning to:
