It’s like the old joke from 2 or three years ago regarding why “Star Trek” will never be a reality.
1. The transporter – All ya gotta do is transport to the Met Museum of Modern Art in NYC, steal all the big $$$ paintings, and retire. Nothing you ever own will ever be safe again once the transporter is invented. This works just as well for TT-O’s methods as well.
2. The “Holodeck” will be the last invention of Man. Think about it.
So why wouldn’t Time Travel? Human nature. Ever meet anyone who didn’t wanna be somewhere/when else?
