There is a "Starship" planned to make a test flight in 2020 and a Mars trip in 2022. These will be Direct flights with a near earth orbit refuel from a Tanker. It does not need the extra infrastructure to make this trip.
The aim of the planned 2024 manned expedition to Mars is to create a fuel depot and refuelling centre on Mars. With that in place the transportation is ready and the other things can follow if there is a political will or economic rationale for that. The same technology could be used for Moon bases and spacestations also.
So you are wrong , this can quite easily be separated off from grand dreams of Moon bases, Big wheel space stations etc. This is important because breaking down the costs of each project into separate budgets makes it more likely that each one will occur. But yes my hope is that we will have all three, Moon bases, Space stations AND a Mars Colony.
There is a hard core of people who have always supported space travel and there is a large alternate group who always try and divert the funds away from it. That space has now gone private means that it is more likely to succeed as it is no longer a question of securing majority support, or political backing but rather of establishing a workable business model. Given that the market is there and the technology is there this now exists
