Granted, I should have been more precise.

Am I right sensing certain hostility to private industry 
as expressed in your texts? I think them being private
and lining the pockets of their directors is not the issue here.
The issue is if their operation in space does forward building
interplanetary space infrastructure than can in turn facilitate
human settling of the system and possibly make us capable of building
a starship if we will seem it reasonable.
The pockets of their directors are not especially important here,
or rather, a possibility to line appropriately these pockets
is a necessary requirement for the industry to be able to exist
at all...

Yes, that was my point, roughly - that the rather Earth-bound
"space" indusries, like commsats & the like, and possibly
space tourism too, may have little impact on building a space
infrastructure needed for eventual starship building
(but see the clarification below).

Some clarification seems necessary.

Namely, I do not postulate to build space infrastructure
just for the reason of preparing to build a starship.
I simply say that building a starship will not be possible
without prior building of such the infrastructure.

The infrastructure will be build for quite other purposes,
the main of which is to allow humans settling the system,
in space colonies and/or on other planets & moons.
Thus, I do not expect or demand from space tourism companies
to build starship shipyards, but only to put enough people 
and structure in space so that starting space mines & industry
becomes cost effective, for them and for prospective miners.
Then it will be no question of *using* these industrial facilities
by "anyone else", but the question of paying in cash for their 
products, which I think the owners will be quite eager to accept. 
That can start the construction of the infrastructure,
provided the tourism companies can & will "grow to such an extent".
