I fail to see how this is a "privacy disaster." It looks like crypto brokers are going to be treated like all other brokerages.
Do you also call it a "privacy disaster" when your bank account requires your name and address so they can report interest payments to the government? Or when Robinhood/Schwab/Vanguard/Etc send the IRS a list of all your stock transactions for the year in a form 1099?
Bitcoin is basically digital gold, and just like with gold, when you chose to buy or sell it the convenient way (eg. through an ETF instead of actual physical gold), it gets reported to everybody.
You can always custody your own bitcoin and find partners to transact with directly and choose not to report it (like with physical gold), but, similar to physical gold, it will be extremely cumbersome, risky, and not worth your time to do so.
