Why any transaction dont include the final balance of each address?

That would be much better to get the balance of any address, just need to find last move in blockchain and dont need to recalculate entire blockchain.

That value can be cryptographed with blocks data, so it would be reliable and we could start to delete old blocks that are just wasting space in blockchain and finally descentralize the blockchain, because sometime only microsoft and google can manage to keep a full node.

Also it will contribute for anonimity because if we generate many. many, many transactions and blocks, no enterprise in the world can get registry of all blocks, like Craig Wright said, the best protection for anonimity is to much data generated like gigabyte blocks.

With possibility of deleting old blocks and even force first blocks to have a maximum time of some years like 10 or 20 years or less, we could have onchain big blocks decentralized and dont need layer 2 or layer 3 or layer 4 !

Would be layer 1 completely descentralized and guaranteed anonymity.
