Cost to reorg the chain is huge, would require lots lots of ASICs, stable source of electricity & large warehouse. Heat & noise are also issues.

Rehypothecation & custodian rugpull risk could be mitigated by storing sats self-custodially. Techical expertise required have been going down over the past decade.

Price suppression is not an issue when buyer immediately withdraw sats to their self-custodial wallet. Exchanges eventually runs out of sats to sell. They can't print it

Legal restriction ? Can still buy sats through P2P markets, VPN & TOR will help.

Mining disruption ( ASIC confiscation, heavy mining tax, rising electricity bill ) ? Green & waste energy, basement mining, USB mining, or just move to friendlier jurisdiction ( hardcore scenario ).

Price volatility ? Sats could be pegged to specific fiat self-custodially by opening short 1× position using DLC on LN

Chainalysis ? Tbf i don't think they can track LN payment easily as long as there are enough hops in between.

CoinJoin, route-blinding, payjoin, splice in & loop out, not reusing address & maybe privacy-specific layer will help

Shrinking block reward will force miner to mine as eficiently as possible. Might be the catalyst towards greener future

Insanely-powered quantum computer that can brute force bitcoin key eficiently ? We are gonna need more words lol, also LN is immune to this imo since SCB is basically superior form of passphrase

Encryption break ? HARD FORK BABY !!

Eclipse attack, Sybil attack, meteor ? Not sure
