1) Where is the complexity?

You've invoked a global surveillance state to prevent forgery. It has no solutions to dealing with forgery once discovered. It requires, in a nutshell, a DMV... and the reason we don't have DMVs for anything without tires and license plates is because if DMVs could be any simpler, they would be. Fundamentally, the DMV is the interface between "your car" and "your government" and blockchain eliminates any need for a government.

2) What's the hang-up on databases?

You're like the fifth fucking person who somehow thinks that a .csv or mongo.db somewhere has any sort of advantage of any kind anywhere ever. Do you guys think we just invented databases or some shit? Do you realize that databases are older than wristwatches? Do you guys honestly believe that an entire industry has been somehow oblivious to technology going back to the Jacquard loom and should somehow go "oh yeah totally our business would somehow be so much more streamlined if only we ran on MS Access?"

3) How can I make the fundamental baked-in advantage of a ledger any clearer?

You don't need to edit SHIT. You just need to write it the fuck down and then control who can read and who can write. Read: the stakeholders (purchasers, sellers and servicers of watches). Write: the seller. Indelibly. Eternally. YES. The key is "really just the same as a password." NO. The password on a blockchain is absolutely fucking nothing like the password on a database. For one, with a database there's a bunch of passwords somewhere. Sure. Salt 'em. Sure. Hide 'em. Sony will still store them in plaintext, Experian will put them somewhere they can be snuck out the back door, everyone will leak them. With a blockchain? I know my password, and to everyone else it is unknowable. YES: if Rolex loses their keys the whole system gets funky. So... don't lose your keys, Rolex.

4) How can you not get this is a very real problem with a very real solution that is in the process of adoption?

I'ma blow your mind. Got a Patek Philippe? Got a Vacheron? Got a Jaeger LeCoultre? For anywhere between $250 and $500, you can write to those companies with your serial number and get the full service and sales history of your watch. See, the high-end companies have been keeping track of this shit from the jump. Fuckin' Vacheron Constantin can look your shit up back to the French & Indian Wars. Here's the catch: they assess that performing this service for you should cost about as much as buying a Shinola. Which might have something to do with them putting it on the blockchain in 2019.

Look. Your opinion is crystal clear. But I'm running out of ways to point out that it's uninformed.
