So you'd like to effectively kill the bulk of R&D in aerospace and throw the economy into a rapid tailspin with the immediate loss of highly-skilled workers in the science and aerospace industry. Nice move.
You think the private sector is going to fund R&D? Guess again. The private sector can't see beyond the next two quarters. NASA, on the other hand, plans at least a decade in advance.
And while we're on the subject, perhaps you should spend a little time learning about how NASA Spinoffs benefit business and consumer alike.
Space travel won't really be profitable until somenone figures out how to make spaceships that can (Safely) travel much faster than the speed of light.
What you're talking about is space travel via teleportation using coherent light as the means of transmission. We can't do that...yet. But that doesn't mean we should just sit on our thumb waiting for the canonical Holy Grail.
As for going faster than the speed of light, there's chatter about such things, but it's still in the realm of fanciful theory. And even if we did manage it, the whole issue of relativity that sci-fi shows conveniently ignore would become manifest in short order.
