He is lying. It is easy for a dictatorship to destroy cryptocurrencies. Most people know that the Chinese Communist Party has GFW, but few people know that they have stronger means than GFW, the whitelist mode.
In fact, I think he spoke in accordance with the data and facts that exist in the current conditions. No one can stop bitcoin and that is true even Satoshi who can create bitcoin in the end cannot stop bitcoin that already exists and runs today.
The government has power and I agree with that but in the end none of them can stop bitcoin including countries that do have a big role in the economy such as the US and China and Russia will not be able to stop bitocin because they will continue to move according to what was planned from the beginning where it will be completed even 80 decades from now.
We can see how government propaganda does its job as when China banned bitcoin from circulating in the country. But in the end it will only be able to weaken the market value but cannot stop bitcoin.
