@Eti First of all, I think we fail to understand what space travel is. In its basic form space tourism is human space travel for recreational purposes. There are several different types of space tourism; including orbital, suborbital and lunar space tourism. So as far as one travels to space for recreation, this itself is space tourism. Sky diving can also be defined as space travel.
In its entry phase, space tourism can be done with balloons (a good example is Space Perspective https://www.spaceperspective.com/) and the mature phase can be a travel to any destination in outer space. So the thought that there is lack of resources in space travel is entirely wrong. And just to prove you wrong, I would like to invite you to travel to our Masai Mara National Reserve (http://www.maasaimara.com/, https://www.maraballooning.com/) and request for a balloon ride. This becomes the begining of space travel. Also, this can be further simplified by a visit to the space museum, the space city and/or the space port, just for one to have a glimpse of what to expect in future. To a person from a developing nation, the kind of experience one gets from this simple form of tourism can be equated to the ‘Overview Effect’ experience.
So let us not mistake ourselves by thinking that space travel can only be for the rich and wealthy and a business venture for the ‘Jeff Bezos’ and ‘Richard Bransons’. Let us start as low as possible by giving a chance to a common citizen who thinks that we are only bound to be born and die on Earth, one who is so ignorant of the existence of a space port within their own country, one who has been brainwashed by religion to think that going to space is in itself challenging God, one who thinks that only Earth is breathable/liveable and that by going to space is in its basic form a suicide affair.
That is the only way we shall unite citizens of the world and have a common front when we build those ships and sail to other worlds.
