I'm sorry you have been tricked into thinking that BTC is "Bitcoin, a peer to peer electronic cash system".
Please consider reading the white paper again and ask yourself what it is describing.
I'm still supporting the very same coin I got involved with in 2011. The BTC camp are working on something else. They have managed to keep the Bitcoin name as used in popular culture, but it doesn't have the same characteristics as the Bitcoin I started working on in 2011. That Bitcoin is now called Bitcoin Cash.
If we strictly define what is/isn't Bitcoin based on white paper, then neither BTC or BCH is "Bitcoin, a peer to peer electronic cash system".
I don't see "one-CPU-one-vote" idea realized by BTC or BCH.
The proof-of-work also solves the problem of determining representation in majority decision
making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone
able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority
decision is represented by the longest chain, which has the greatest proof-of-work effort invested
in it.
