Categories of Gold buyers

I feel there are four categories of gold enthusiasts, correct me if I am missing anything.

1) Hobbiest: owns several coins mostly for their historical context.

2) Emergenciest: owns several coins In Their go bag for when it’s time to go.

3) Prepper: owns a years income in gold to withstand the coming chaos.

4) hard moneyist: has nearly all savings in gold because you can’t trust anything else.
