Personally I would also love to see real BTC/Stock pairs (I think there was an exchange in the past kinda offering this, but required kyc, forgot their name) but I highly doubt we will ever see this in a decentralized/kyc-free fashion (probably when hell freezes over )
There are decentralized finance platforms trying to bring stocks into crypto. Mirror Finance on Terra is the biggest one that I'm aware of, and it operates on a similar model as Dai does by having users overcollateralize another coin in order to mint a stock token. It's not quite real stocks, and it's not directly with BTC, but it does seem like a decent bet for anyone wanting to buy stocks without going through KYC.
I don't think we'd ever see a platform with 100% real shares, so the DAI model is probably the best we'll see for decentralized stocks.
