He's one that is only accepting money orders as @jeep78 mentioned so he's going to be fishing from a smaller pond...
I personally wouldn't buy anything online with a money order.
I can see both sides of the fence with this. I sold an HK SP5K and specified MO only. As I was unfamiliar with Cashapp/Venmo/Zelle at the time, my only other real option would be Paypal. If Paypal was to find out and they locked my account and my money (over $3K), I'd be screwed.
Everything went without a hitch but you're right, it was a smaller pond.
