I don't have timw to write an elaborated answer, I just see a lot of things to clarify for kyphysics. Regarding the intrinsec value of bitcoin, you can think of it a bit like a wikipedia hosted on millions of people's ''servers'', where each entry is a bank account. You can only edit your own entries, to send money to other accounts. There's no known reasonably feasible way to hack the system by taking control of ''the server'', for there is no such thing (it would mean performing a 51 percent attack). If you don't see any value to such a system, then fine, you're like millions of other people (see r/buttcoin). If you think this has value, then fine, you're also like million of people.
Regarding your hacking question, I suggest you to read about hardware wallets. The hack you mention cannot occur on them, they are completely disconnected from the host pc, except to transfer a file (that you sign using your hardware device's buttons, this cannot be keylogged, but of course there are ways to get your seedphrase). No internet connected, and you should never, ever type your seedpbrase into your computer. The seedpbrase is a ljsf of 12 to 25 words, most if nkt all of them picked randomly from a well known list of like 5000 words. Then an algorithm translates your words (and their order matters) into the private key of your wallet on the blockchain.And.a.comment regarding that bitcoin was made to be anonymous or opaque, this is wrong. Nakamoto was well aware of privacy concerns, and he found no better than to suggest the use of a different wallet for every transaction (this did not aged well), he wasn't a privacy expert. Monero came up with better ideas in that aspect.
