When people discuss being "pro-bitcoin" for other reasons than speculation, they always talk about the practical use case for blockchain tech...everything from secure authentication to free speech protection, and all those things sound great and one can see the potential for blockchain in those areas.

But whatever the use cases for blockchain eventually are, why would the bitcoin protocol in particular stand a great chance of being any part of them?

This is what I don't understand about any kind of longterm bull case for btc.

The bitcoin blockchain protocol to my knowledge cannot be optimized in infinite ways. This alone makes it very likely to be surpassed.

I'm no expert. Maybe I'm way off base here.
