Yes, interplanetary travel is too expensive.
Paying an entry fee just to be allowed to spend my money somewhere is plain wrong, especially on the internet, when there is absolutely NO physical reason to charge.
On CP, a potential reason to require travel to CP by ship (and at a cost) could have been to keep "sweaters" away from interfering in the domes. "To keep the riff-raff outside", so to speak.
For CND, it was designed as it was for, in the bottom line, be able to recoup the purcase cost of the asteroid itself by selling apartments. Hence, originally no TP or storage.
For places like Rocktropia, *beside* from making hangar owners happy, there is no reason for the fee - at least for us who joined by ourself and wasn't recruited by a specific "planet". Who joined when MA and FPC were a single company and it still was called "Project Entropia". For us, travelling to Rocktropia shouldn't be more expensive than it was to travel to Treasure Island in VU 9. So you can't use the argument that, for instance Neverdie, spent marketing cost to get me to join *his* planet and that I should be confined there unless I want to pay a huge pile of cash to "move".
