Sadly, it will be a series of crisis that humanity is to experience that can put Bitcoin into the mainstream as a currency and a safe haven. Under any circumstances, Bitcoin is beyond the reach of any government or legacy financial institution. No government can declare Bitcoin to be under the control of the government...they could not devalue it by decree or can they confiscate away from you just like what some governments did to bank accounts of their own people. And we can clearly see the many reasons why Bitcoin is a lot better than fiat during chaotic times.
