To ask you: do you want to create a new system or fight existing one?
If you want to fight existing one, good luck. In the new system, there is no fungibility problem. And you don't need privacy coins.
You only need to change your mindset.

I'm in Bitcoin sincs 2013, have no bank accounts for me or my company. I use cryptos on daily basis for my comoany and personally.
There is a fungibility issue and a huge one. As long as someone can say I don't fake your UTXOs because of their history tgw whole think doesn't work.
We need cash which is fungible in digital form which is Monero.
Why wouldn't I 'take' your UTXO?

How might one change their mindset in order to effectively prevent this from happening to them?
