The main constraint on the Super-Heavy booster is ramping up the production of the Raptor engines. They will need 100 Raptor engines to get to the orbital test. They build one Raptor engine currently every eight days. On 2 months they want to get to one Raptor engine every two days. By Q12020, they want to get to one engine every day. This means the orbital flight would not be until about March, 2020.
This would be ahead of the Space Launch System launch which is looking like 2021. This should be ahead of the green run hold down fueled test of the Space Launch System.
SpaceX wants to be able eventually refly boosters up to 20 times a day.
They will fly the Starship about 3-4 times a day. The orbital limitation is about the orbits. This would not be a limitation for a point to point version.
The fully reusable fleet of Super Heavy Starship will increase humanities launch capacity by 10000 times. This is max theoretical.
With 20 rockets you could put 3 million tons per year into orbit.
