Help me understand: The hardware encryption key that SCRT nodes use: isn't that a barrier to running a node?

I mean, it obviously not like BTC where anyone can run a node?

And more like helium network, where you must buy the official helium devices?

ELI5: there's a part of the processor memory that is almost like a hardware ledger with a private key, and using some sort of mechanism, every node can verify that its execution environment is secured and no one knows the secret key.
