Question about double spending and the "Bitcoin puzzle transaction ~32 BTC prize to who solves it"

If someone eventually managed to brute force Puzzle number 64 (and beyond) can't someone who's monitoring the keys just use Pollard Kangaroo once the public key is broadcasted and also sweep it with a higher transaction fee since double spending is still an issue with Bitcoin? If thats the case how can you prevent someone from sweeping the same key if you're both in possession of the same private key?

Bitcoin crashed from ~$750 to ~$100 almost instantly following a bitcoin exchange claiming the protocol is flawed allowing double spending along with a huge 4,000 BTC sell.

People watching live were freaking out
Looks like the protocol issue has been known and the exchange is looking to blame not accounting for it on Bitcoin itself.
Calls for the guy who made the protocol statement removed from the bitcoin foundation met with commentors calling the foundation a joke
Tin foil hat time
All of /bitcoin is basically drama right now.
SINCE I KEEP GETTING PMS FROM NEW PEOPLE WHO CAN'T READ ON THIS THE PRICE CRASHED TO AROUND $100 AND THEN SHOT BACK UP TO $650. IT DID NOT JUST CRASH $100

I sold my BCH into a dip. This recent possibly hyped double spend of BCH and the whole shambles that took BTC down so far was caused by Bitcoiners wanting to hang onto their fake BTC. Look at this SV crap... If BCH was disowned and discarded burned from the start then we would be several hundred percents further along with our goal of not being rich but having a credible monetary alternative.
Isnt that the goal?

The novelty of the Bitcoin protocol is how it solves the double spending problem for online commerce. Replace-by-fee (RBF) makes double spending new BTC transactions trivial, robbing Bitcoin of one of its most useful and innovative features.

Satoshi's novel innovation was how he solved double spending for online commerce in a decentralized manner. A basic premise of the Bitcoin protocol is that the longer your transaction sits in the network, the lower the probability that someone can double spend. This includes 0-conf transactions. RBF breaks this crucial premise entirely, as you can trivially include a higher fee, double spend transaction before the next block is found. This forces merchants to wait at least 10 minutes (if the BTC network doesn't have a clogged mempool, or your fee is high enough) in order to be fairly confident that the transaction is valid.
If you're unconvinced, please read what Satoshi himself had to say about accepting transactions within a 10 second time period.
