Breaking the private keys to the concentrated wallet(s) targeted not the entire system. Easiest way is finding/stealing the keys but eventually over time compute does break encryption and keys made with those algos are no longer "secure". There may even be ways to target earlier keys easier than later. It could take decades but it will happen.
Are you suggesting as processing/compute increases, encryption doesn't get weaker from previous algorithms? 40-bit SSL certificates, Triple-DES encryption and MD5 + SHA-1 hashing would like a word. AES-256 could outlast the universe but that is based on our current knowledge, and sometimes encryption systems have doors, not only in the algorithm but the tooling that does the encrypting... the creators of bitcoin tools they used for keys may also be a weak link or even had doors they put in themselves as a failsafe, humans tend to do that due to game theory.
Encryption is a balance of compute/processing for encryption and decryption, too intense and the system is computationally too heavy. So with that, over time all encryption will be able to be broken at some point following, as history has show so far.
Even if that holds, the chance that someone finds the keys or tracks them down, might be faster and most likely will happen as time goes on.
The point being mainly that too much concentration in any financial system is a time bomb.
