That's dirt cheap by many standards, meaning satellite launch will be much easier and relatively cheap. The key word here, though, is 'relatively'. It will still take large amounts of money to put people in space on an absolute scale, and we're never going to have millions of people traveling there on a regular basis without a step change in technology (e.g. elevators or catapults or the like)
Cheaper launch costs are great, and I see them being valuable for developing outer space industries - e.g. Trojan asteroid capture and mining, space stations and crewed missions for exploration, etc. But while Earth orbit and the solar system might get a bit more crowded, it's almost entirely going to be unmanned. Space tourism and the like will be the preserve of the very rich.
