WHY spend million$$$ to build "spaceports" ???

when suborbital planes with jets (like the EADS Astrium design) will
be available, every small jet-executives' airport around the world
will be sufficient for takeoff and landing

Incorrect and clueless again.

suborbital planes use propellants which small jet-executives airports
are not sited for, hence the need for spaceports

Suborbital is not orbital or trans lunar or trans planetary...

Although, a ship capable of 1/3 gee could take off with wings on Earth
and land vertically on the moon under rocket power - and take off - in
1/6th gravity - if it had the specific impulse to do all that in one
stage AND carry the wings along.. hmm...

the jets will use kerosene and air, while, the (so far unveiled)
rocket engine could use kerosene and a small amount of LOX pre-filled
at the EADS planes' headquarter base

More than a "small" amount and no such thing as " pre-filled". It
has to be filled at the takeoff spaceport

LOX isn't that hard to deal with, but I don't believe it's something you'd
normally find at an airport.

Beyond that, until operations expand beyond a handful of airframes, it's a
lot easier and cheaper to keep all your maintenance crews at one location.
Working on rocket engines isn't something your typical aviation mechanic has
experience with. Something like a bit of contamination in a LOX line can
spell disaster for a rocket engine.

However, not necessarily all that difficult for airports to provide either.
LOX is cheap, fairly easy to transport (or even make on-site).

yes, the LOX refuel for the small EADS plane needs a very little
"infrastructure" that be moved from airport to airport with a van

The airport still has to be sited for the LOX and the plane. Also
moving the van is not efficient, since the plane is going all over the
place

the EADS plane will be a very common executive jet able to fly
suborbital, then, it can fly from airport to airport with the only
need of kerosene refuel

the "van" is a only a metaphor to say "so small every place is good
for it" ...also the smallest airport is several sq. miles large, so,
every airport of the world can host the van-like small
"infrastructure" to refuel the EADS plane's LOX tank (assuming it
needs a refuel, while I think it will come prefilled from the planes'
headquarter)

you may like it or not, but THAT is those will happen since it's the
most obvious and RATIONAL choice

so, all "spaceports", after a few years of success, will soon become a
desert, since the suborbital flights will start from hundreds
different places
