So now they ask a full node for merkle paths + t= ransactions for the
addresses from the UTXO set from the block(s) that it was found in.

This is the part where I get lost. How does this i= mprove privacy? If I have to specify which addresses are mine in this block= , to get the tx data, the node learns which addresses are mine at this poin= t, no?

Also, are you saying each block needs a rec= ord of the entire UTXO set at the time the block was made? I'm not sure= how to parse this sentence.
