There's a 0% chance of a successful colony, by any definition of successful, on Mars in the next century. If we, as a species, cannot avoid destroying the climate that birthed us over millions of years we have exactly 0% chance of surviving one that is completely inhospitable to life.
This speech by Colonel Jessep is meant to be revealing of his true thoughts and character. Jessep rationalizes the evil and immoral acts he commits or orders because he's "protecting" the rest of society. He lied to cover up his own malfeasance. A soldier died under his command, murdered, as a direct consequence of illegal orders he gave.
How do you completely twist the plot of this movie to arrive at the conclusion that Colonel Jessep's worldview is one to be admired instead of reviled?
So... what happens when the person who originally deployed everything eventually leaves or gets hit by a bus? Hey, it's six months later and you need to redeploy everything again.

"R0 is not a biological constant for a pathogen as it is also affected by other factors such as environmental conditions and the behaviour of the infected population." [0]
If we hold R0 down long enough through change of behavior then we can absolutely flatten the curve.
Of course you're some newly created sock-puppet account too afraid to post under your real handle.
COVID-19 will absolutely cause the death of millions in the US alone if proper steps aren't taken to reduce R0. If not from the disease itself, then from hospitals being completely overloaded.
Edit: Let's be real: lockdown/isolation is going to have to persist for at least a month or more to have a real chance of preventing the spread to most of the population in the US. 2 weeks is not going to cut it.
