- privately dismissing it,
- publicly dismissing it advising others to do the same,
- publicly & actively attacking it, going down in history as an enemy of Bitcoin (zenith of stupidity).
- 2nd, they can't replicate Bitcoin's "immaculate conception", they're compromised since day 0, by definition.
- trustless nSequence-based payment channels, + on-chain settlement (Satoshi),
- few big "masternode" enabling trustless SPV via fraud-proofs (Satoshi),
- trustless pruning: nodes get/verify only recent information, discarding all the old information eventually (Todd, Maxwell, alt.).
- trusted 3rd parties turned out to be a systemic risk,
- nSequence channels idea was broken & we had to wait years to be fixed (SegWit+LN channels) & improved (LN trustless onion routing),
- trustless sharding (aka Sidechains???), while being sold as a buzzword by Ethereum scammers, is still a difficult/unproved topic,
It takes a stupid to think that difficult problems are magically solved just by some (smart) idea.
- Bitcoin mining isn't (yet) illegal in China,
- Bitcoin users can sync even without using Tor because Bitcoin is not (yet) fought so hard by government, etc.
