Could Blockchain Still Work Perfectly without Mining?

[Suba]

We know that the max supply of crypto PoS is almost reached, (Btc, Ltc etc) means that if the max supply has been reached there will be no more crypto mining activities, so miners only get a fee from the validation process and transaction confirmation, the more miners the more difficult the hackers cheating on crypto transactions, what do you think after there is no crypto mining, transactions are still safe and the blockchain can still work perfectly?

Yes it would but it would be limited to some people as in those that can actually afford buying crypto currency on either weekly or monthly basis. Mining makes it easy for anyone notwithstanding where they're from to mine easily and get their returns at the accrued time
