You are wrong. If a person could really "crack the code and do what he wants" (which is very, very unlikely), then they would have already spent at least some of the funds from the given address. Or better yet, why not crack some of the addresses that contain thousands of bitcoins, like Binance's cold wallet or some of the other Bitcoin Rich List addresses?

No, what you are looking at is a "burn address" or "black hole" address. It's a valid address, but nobody has their private key to use in order to spend the funds from that address.
