I personally have felt positive things from the existence of this cryptocurrency industry, so I actually don't agree if, for example, our country prohibits activities in cryptocurrency. Luckily our country doesn't ban it, so we can still trade and invest in crypto.
Maybe in the past the countries that banned crypto saw that crypto was not useful or would be detrimental to their country so they banned it, but after seeing the huge development of crypto they changed their minds.
Years ago, for example during the bull run 2017, the focus was solely on blockchain technology: countries and companies wanted to use blockchain for supply chains or decentralized data storage for healthcare, transportation, education... Currently, blockchain technology is more developed, but its adoption by businesses is still not really widespread, only some private blockchains have been tested on a small scale. In the meantime, crypto has developed strongly and is seen as a new market, a new asset class for investors.
I'm not sure if governments see the value of crypto to the economy, but they have at least recognized that taxes from crypto can help the country develop better. Crypto adoption can also create jobs, attract investment, and get votes from young voters - these are enough to make politicians think seriously about a national crypto strategy.
