In the far far future, could Bitcoin be destroyed by ideology?

I was just going through a thought chain about the consensus mechanism of Bitcoin — the fact that 50.1% or more of all nodes is needed to implement … new rules?

(What is the limit on what can be changed, as long as there is a consensus from all nodes?)

And I was just imagining a future where Bitcoin indeed rules the world, it is the main money system everywhere and everybody uses it and have long forgotten about fiat, because fiat is history and we’re so far to the future that everyone grew up with bitcoin and it’s standard and normal.

What tends to happen in society (as could be argued is also happening now) is that people produce ideologies that aim to take down what’s most established. “Because what’s most established must be the reason for all of our suffering!” (common ideology viewpoint imo).

Well - at some point Bitcoin might be what’s most established.

Bitcoin might be what people look to and say — we need to change that! The rich can’t be that rich, just because they were first movers, and fuck money and fuck the (Bitcoin) system.

An ideology spreads to the whole world, and people with nodes (more than 50%) agree to a change.

In this case, what’s the potential biggest disaster for Bitcoin?
