It's a good thing community is starting to understand the threat to Bitcoin world BRC-20 brings. I actually can't wait for Bitcoiners in the US to sue Casey Rodarmor and Domo for all the losses their inventions caused. 
Ordinals didn't cause any loss, it wasn't an attack that compromised the network or people's wallet, not that it is even possible, so what has a lawsuit got to do with this. BTC is even a decentralized currency, so if you ever lose BTC in your self custody, no lawsuit can help you recover it. Ordinals truly takes up block space, but it isn't a threat to BTC; it only causes mempool congestion and makes people to pay higher tx fees to outbid others and get their transaction confirmed, it is surely going to cool off. You are contradicting yourself here. Ordinals caused (and continue causing) huge losses. People who paid cents (satoshis) for their tx are now paying much more (x10-x100) for the same tx for no particular reason. This is because the network is getting ddosed by the NFT criminals.
Putting pressure on the owner/inventor will make him feel the pain regular users feel because of his invention. I think it's quite fair and no need to introduce any limits/bans/censorship on the Bitcoin network.
