Will there be a way to exit without selling to fiat

I’ve been thinking about an exit strategy plan for a while now, and trying to find ways to realize my profits towards the end of the next bull run without having to sell for fiat and pay all the taxes. I know the current financial system wants to avoid direct links between crypto and the whole financial system, but I really hope we will be able to buy composites and stocks with crypto directly. I’m looking for an option to buy gold for example pe with crypto to de-risk my portfolio when opportunity occurs. I would like to ask anybody with any knowledge or insight about this possibility to share it please. Is this an unrealistic expectation or there is a legit possibility for this to happen?
