The work is invented on purpose... Key word is PURPOSE rather then "for the lulz".
The "invented" work is also known as cryptography and its purpose is to stop anyone from printing infinite coins as well as to ensure the system is unadulterated by fakes.

Its bad enough when the government is printing infiniate money, give that power to every citizen and you got a worthless "currency".
Can you come up with a way to ensure every living person only has 1 wallet? (answer: no... unless you are the government and institute some strict biometrics)
