have you seen lord of war? close a stretch of highway and boom, airstrip.
Yes, you're describing the creation of an *airport*..albeit a shoddy one. Even a makeshift spaceport would still be a spaceport--a place for craft to safely land and be attended to. If you want many craft to come in daily on the scale necessary for mass industry, youre going to need support infrastructure, to safely direct traffic, move freight, service the craft, etc.
On the speculative side, a spaceport in this universe probably requires both a ground and an orbital component. Larger ships cant land in an atmosphere with gravity or they'd break apart under their own weight. So they'd be forced to shuttle down cargo bit by bit, or drop them for orbit, neither of which seem safe or efficient as an ongoing proposition.
