Re: Why any transaction dont include the final balance of each address?
what you are describing is no longer blockchain and has no cryptography involved anymore. it is just a database like what banks have where you own an account which has an associated balance with it. and unless you can find a way to decentralize it and include cryptography in it so that there is no way of cheating that "balance" without needing a centralized entity to update these balances and control fraud, you won't be able to implement your idea.
because that is where we land with big blocks, a handful of nodes run by NSA which you have to connect to.
like Craig Wright said, the best protection for anonimity is to much data generated like gigabyte blocks.
yes, the best way of remaining anonymous according to Craig Scammer Wright is to always connect to NSA and report all your activities down to every detail willingly because that is where we land with big blocks, a handful of nodes run by NSA which you have to connect to.
Yes it can be a blockchain, there still will use math and math is math, 2+2=4, its like the block criptography, just will have the total account balance as more a variable to be encrypted in data block and cannot be changed without redo all calculations again, same thing as now in blocks cyphers.
besides if you want to do a change like this, you have to basically rewrite bitcoin and kind of fundamental change will never happen.

NSA can run nodes too, everybody knows bitcoins its not 100% anonymum, if you want privacy should be better to start to delete first blocks.
first of all the difference is that if we have gigabyetes of block only a handful of super servers can run bitcoin nodes instead of individuals on their personal computers and that will centralized everything.secondly it is not only about privacy, it is also about censorship resistance. with a centralized system, those servers can force anything they want on you and you will not be able to do anything about it. for example they can decide transactions that come from your "account" are illegal and ban you. effectively that will lock your funds up. or they can ask $100 fee per transaction to be paid to them separately. you can't do anything about any of that because there are no other nodes. there are only these servers and they decide the rules.
and that is just some of the examples off the top of my head.
