Bitcoin is very sensitive and can have strong volatile due to fiscal policies or the financial markets as you said. However, those are just short-term volatile, but if we zoom out and look at the bigger picture in the long term. I think bitcoin is still a good inflation hedge.
Looking at the chart, we see that bitcoin's growth rate is impressive over the long term, and if we think it's not a good inflation hedge, that's not fair to bitcoin.

Objectively speaking, gold has a far longer history and has been through several economic cycles. At the current stage of Bitcoin’s growth, I wouldn’t consider it to have gone through more than one economic cycle.
If you’re actually looking at the long term, I would extend it to a few decades. Bitcoin is quite subjected to information gap, and that’s why you see the trend for Bitcoin to be increasing year on year. People find Bitcoin to potentially be a better currency and they decide to invest in it as time goes by.
Remember, economic cycles lasts quite a couple of years. It would only be fair after it has been through a few, and that adoption is stable.
