You do realize that Bitcoin, and Monero are both Proof of Work hashing algorithms, so the 51% vulnerability are shared on both. While it’s more plausible that a 51% attack could be achieved on Monero, the fact a incident similar to that with selfish mining has occurred, the devs have been considering different mechanisms to counter act both attacks. But yes hash rate is probably Monero’s weak point primarily due to its algorithm being focused on CPU mineability but I think a strong coordination of the monero community could counteract that.

Yes I've been involved in Monero since before Monero existed (the cryptonote/bytecoin days). The hash algorithm and trivial amount of energy required to destroy Monero is exactly why governments are unconcerned. To them it's even less threatening than tornado cash. As soon as you need to rely on the community to change the hash algorithm it becomes even easier for the State to kill it, infiltrating communities to destroy them from within is where they really shine. It truly was a fun experiment but the reason you don't want an asic resistant algo is because the State is the adversary.
Monero's CPU focus does make 51% attacks more plausible, but its dynamic PoW algo (RandomX) actively discourages ASIC dominance, which Bitcoin fails at. The selfish mining incident was mitigated via protocol updates—shows adaptability. Re: hash rate vulnerabilities, reminds me of how AI systems face prompt injection—seemingly small flaws with cascading effects.
It discourages the *market* from developing asics, it encourages the a State because developing an asic is a guaranteed kill shot. They may have aleady done it just in case Monero catches on and they need to tank the price so everyone moves to cuckzcash or some other controlled opposition.
