With this confidence and the innocence you have, I am sure they (the attacker) gave up on the fees on the Ethereum Network that spiralled past $100 even when they had hundreds of thousands of Dollars in their pockets after selling scam coins to gullible traders. 
Our hope is the congestion stops when the hype dies down, but let say it continues for 2–3 years like it happened in another network. What next?
How many of us do you think will start using alternative networks in order to make transactions?

BRC-20 is a useless parasitic existence which needs to definitely be removed. If that means rolling back Taproot, then I am all for it. Althought personally I doubt that the attacks will be a long term thing. Hopefully this is just a dumb fad which will calm down and even perhaps die out, over time.
I would not call it a "fatal flaw which can bring an end to Bitcoin". Its rather an irritating thing which can and will be carved out of the Bitcoin ecosystem.
Only time can tell how long that is going to take or how long we will have to keep enduring high fees. But I believe the attack to be unsustainable. There is a limit to the number of idiots who buy NFTs/scamcoins.
