Mining VS Puzzle Dificulty

[entropybit]

Puzzle 66 is more than 2 years without anybody being capable to find its privkey, but compared with the dificulty to mining a block is exponentially easier, why no one put their power hash machines to mine BTC puzzles?

For exemple a mining block hash is
00000000000000000000 53795dbe26e2befb0c081e50826c88997900207d4c90

And puzzle 66 is
00000000000000000000000000000000000000000000000 3a838b13505b26867

It is 27x exponentially easier.
can someone go deeper on this analise of dificulty between a block vs puzzle 66?

If you refer to brute forcing address with known range of private key, then it's impossible task. ASIC for mining Bitcoin only can perform SHA-256 while brute-forcing address perform ECDSA operation which convert private key to public key.
