Will the SpaceX Starship change the economics of spaceflight for ever ?

We are aware that Elon Musk's company SpaceX has trying one after the other through several attempts and ideas to extend the frontiers of human understanding of space and its farthest domains. The 119 m tall completely reusable Starship from SpaceX is one such example. 

The commercial space age kickstarted by Boeing, Blue Origin and Virgin Galactic over the past two years has increased the appreciation of space to solve human problems on planet earth. Click here for the HBR  Feb 2021 article that outlines how private interests are taking over the space exploration and travel sector for entertainment and adventure.


The 85 T rocket from SpaceX , 38 stories tall, that carries fuel of 1100 T (240 T Methane and 860 T liquid Oxygen) can carry about 120 passengers to space and back. A fully loaded Starship can go to Moon and return to earth. 
 
All early explorations have been funded from tax payers money by national governments. Over the past ten years we find SpaceX trying its best supplying replenishments to Space Station, located about approximately 500 kms from earth surface.

The reusability feature of Starship will reduce the cost of space travel to a great extent. Pic of Starship at the launchpad. Image courtesy SpaceX.
 
The fact that the new SpaceX Starship can carry about 120 people simultaneously to space and back, a full tank of fuel can take one to Moon and back, promises great forward strides in space travel for the coming generations. 
 
When Yuri Gagarin went to space and completed one revolution around the earth for the first time on 12 April 1961, little did the world imagine in the coming days we would send unmanned crafts all the way to Mars and even to the asteroid belt between Mars and Jupiter.
 
The once mighty USSR (now reduced to Russia) may not offer a credible competition to US, but France, UK, Japan, China and India can in the long run, give competition to US in space exploration. Most of these countries have landed or orbited around the moon.

The Voyager Missions that have crossed the solar system, we doubt, will they be able to throw light on the near confines of space, forget inter galactic space ?

When will the first human spaceflight travel a light year (the diameter of our solar system is just 0.00127 light year) ?
