Look at the code and there's a key difference to notice. While people may be completely retarded with their personal files, putting them on goolag drive or similar centralized service they don't control, for "convenience" it should be said that doing so is exactly like keeping your gold in someone else's vault.

Then there's local storage, anything you put on a secure encrypted disk at home is under your control and secure. But here's another problem, disks are sensitive to damage. If your house burns down you can usually recover any gold you hide in your mattress or your safe, just needs to move all the trash first. A disk on the other hand is destroyed.

Now with crypto and blockchains you'll get decentralized and distributed encrypted storage for your files. This means that your data is synchronized across many disks spread over the world and you're in control thanks to your key, which you can make backup copies of.

Now this solves the recovery issue. If you're out with your boat and have your gold with you, then your boat sinks at the deepest spot in the ocean, you'll know where your gold is, but you can never recover it. With crypto you may have a backup key somewhere else which allow you to access your coins, even if one of your keys sunk with the boat.

Those who want to control you will do anything to convince you that "it's a scam", in reality it's a tool you can use to take back control over what's yours. We can control physical items we own, why not have full control over digital items too.
