1. Yes, again, you cannot fractionally reserve something with a fixed issuance very much until it's obvious you are lying. This isn't gold where the supply is unknown.

2. The money blackrock controls is not it's own, it's the money of it's investors. Mis-managing investor funds is what caused Bernie to die in prison. I doubt Larry wants to share that same fate.

3. this is absolutely incorrect. Again, I direct you to the 2017 fork war where the vast majority of miners signaled on-chain support for the big blocks. But the node operators simply did not update their software to that version, and the rest is history. Stating this claim of yours without supporting evidence and in the face of clear contrary evidence is just you not wanting to admit your fantasy is mismatched with reality.

4. If you run your own node and are educated about bitcoin then you give zero fucks about the brand. I give zero fucks what you call the proof of work chain that I run a node against. It doesn't matter. You can brand your proof of stake shitcoin "bitcoin" all day long I, and anyone else who actually understands the protocol, will never run a node against that network.

If bitcoin is going to be compromised it will be either:

1. soft-forking in some new opcodes that can be co-oped. Covenants are a good example of this. This is a major vulnerability.

2. Hash pool consolation which allows controlling interests to censor the network. This is an attack that is happening now, as we speak.
