I believe it is extremely important to maintain the fundamental properties that Satoshi laid out -- because the system he described is the system that all of us who own bitcoin bought in to.
Do you think Satoshi would still be here had you not talked to the CIA?He has already answered this numerous times and it probably drives him crazy to keep hearing the same questions being repeated.
The answer is we don't know Satoshi's true motivations for leaving but can only speculate.
