Monero's recent delisting on a major exchange ( I think it was Binance, but I could be wrong) is proof of why in my humble opinion should NEVER be made entirely anonymous. This would end bitcoins chance at ever becoming a world wide currency system. Governments already have a hard enough time accepting it as is, if it were to completely become anonymous, making the blockchain private..nearly every government in the world would shut it down. More countries haven't shut down the use of Monero in their nation because it's not real popular. I could go on and on about this, but this is my quick synopsis.
You cannot shut down Monero or Bitcoin, just like you cannot shut down BitTorrent or Tor or any other decentralized protocol running on the permissionless TCP/IP.
What you're talking about is delisting certain cryptocurrencies from CEX and ETF custodians such as BlackRock, which would remove USD liquidity from the ecosystem and cause downwards pressure on the fiat price/valuation. Is that correct?
Do you think Satoshi chose to make Bitcoin pseudonymous and not anonymous for this reason? I mean it could be an argument, that if Bitcoin had Monero's features, then the governments would want to shut it down instead of surveilling it.
Satoshi wanted to implement XMR features on BTC, long before XMR was born:

Did Satoshi care about BlackRock's ETF? Most likely not.
And please stop assuming that it's possible to shut down decentralized, permissionless protocols, because it's not.

Nobody can shut down Monero even if the price drops all the way down to $1 or even $0.01. OTC trades will still exist, DEX too.
