Blockchains are costly and don't solve these problems.
It is as evidenced by the way blockchains are used now. Cryptocurrencies are the most important applications, and few people actually own them, and by "owning" I mean being able to make a blockchain transaction. In most cases, they have an account with a third party who does the blockchain stuff. In other words, a bank. In fact, it may be an actual bank, which is probably for the best because actual banks are highly regulated and are less likely to just take your money and disappear.
Cryptocurrencies quickly became just another financial product that is being integrated in our current system. And for the other ways cryptocurrencies are used, these are mostly illegal (drug trade, ransoms, scams, tax evasion, etc...) and governments are working on that.
Other prominent applications of blockchains: NFT, DAO, etc... are even crazier than cryptocurrencies. All the madness of our current financial system without the regulations that make it somewhat usable to grownups.
