Every effort to create technology or to be a pioneer in something must be driven by a transcendental reason.
I think that "space tourism" is a very trivial reason and is only based on commercialization.
A space trip should serve to provide humanity with great value. To give it life or to prolong life. To evolve.
Just as BTC did, it came to change the lives of people and of all humanity. Change to move forward and evolve.
