I hate when people criticize and don’t offer a solution. The obvious follow up would be to calculate exactly how big of a rocket must be built to reach the moon, or even deep space.
11,186 m/s = 263.1 s * 9.81 m/s^2 * ln( x kg / 20,800 kg )
That's roughly 1.58591*10^6 kg of propellant, which is actually less that what's in the first stage of a Saturn V. Of course, this doesn't include air resistance or anything beyond just hitting escape velocity and leaving Earth's orbit.
