Out of all the factors that you have mentioned here, the major reason that prevents Bitcoin from massive worldwide adoption is the first one. China, Egypt and other anti-crypto countries are some of the examples of this. On top of that, most of the countries are in the ‘“grey” area where Bitcoin is neither legal nor illegal because of its certain risks to protect the investors. Scams and frauds using Bitcoin are also a “concern” too for some countries because it doesn’t require government or 3rd party approval. Government and banks want control of it, but they can’t because it’s decentralized but provides transparency of all transactions where it can be easily traced.
Governments are the ones who're interfering with Bitcoin's adoption worldwide. But they're not the only factors at play. As you've said before, scams, theft, and hacks are also one of the reasons why most people are afraid to use Bitcoin in the first place. While the same thing happens with traditional Fiat, people seem to trust it more than Bitcoin because it's backed by the government. At least, there's been some progress on Bitcoin's mainstream adoption over the past years.
With ever-rising inflation rates from traditional Fiat currencies, more people are beginning to notice Bitcoin's true benefits. We should give it more time to mature until it becomes a "force to reckon with". As long as decentralization wins, nothing else matters. Just my opinion
