in my opinion, because the function of blockchain is not only for the financial sector. a few months ago I read the news that the blockchain was used for elections and that it was one of the uses of blockchain technology that did not require cryptocurrency. or for the health sector, the blockchain will greatly help the government to solve the problem of transparency and security in the health sector. so there is no reason for the government to reject blockchain technology. if the country wants to develop they must not close themselves from technological developments.
That is why you can see lot of country have started to use blockchain technology but they have barred usage of crypto currency. Bitcoin got famous due to introduction of blockchain technology usage if not it would also been an another shit coin in the market and crypto currency would have flourish this much
