I think you don't understand how Bitcoin works.

It's already possible to fully "track/monitor" (without centralization) because all transactions are recorded permanently in the blockchain.

As to "censor" it would not be possible even if Bitcoin was mostly centralized (I assume you are talking about miners centralization). As long as some miners are honest, even if it's a small fraction, your transactions that others attempt to censor will still eventually be confirmed, whenever these honest miners find a block, because given the P2P nature of the Bitcoin protocol, all transactions can reach all nodes.
