A blockchain requires trusting the authority that set it up and/or any authority that can 51% attack it.

If you are in a situation where you can't find any trustworthy authority (including yourself), you are probably part of a scam or a crime.

Byzantine fault tolerance is an interesting concept that solves a problem that almost never happens in modern software.

So, you don't understand how blockchains work, okay.

With a distributed BC you don't have to trust an authority. You trust that 51% of participating entities know what they are doing and that they checked the protocol implementation and agree on one.

A distributed blockchain has code that you have to trust.

Also you can say that everything in a blockchain is verifiable by third parties, but most people don't do that work (not unlike any open-source software).

I don't know why the comment above was downvoted. The parent clearly doesn't know what they are talking about (e.g. in a deterministic setting at most one third can be malicious).
