Crypto currency must solve this problems

I think cryptocurrency must solve the following problems in order to replace the current currency
1. Completely anonymous, one person can have an unlimited number of wallets. Must have a real-name wallet. Otherwise, the future of cryptocurrency is a crime
2. Everyone can issue cryptocurrencies, raise funds, and issue airdrops. This is wrong. Everyone can issue their own currency, which is obviously a legitimate fraud and must be prohibited.
3. Extreme speculation, including leverage, currency speculation, fundraising, mining machines, NFT, etc... What contribution does it make to the real world? I know that cryptocurrency is very profitable in avoiding the law, and it is even the first money-making tool in history. However, those who make this money only make other people's money.
4. Cryptocurrency is the most criminal industry. As long as it is a cryptocurrency crime, it is basically innocent. Do you want to be hurt in the future? Everyone may be the next victim
5. The inequality between those who own cryptocurrency and those who don't have cryptocurrency. I know it’s good for the few people you own, but do you really think it’s right to make this kind of money? Cryptocurrency just creates another kind of inequality
