Imagine your fleet and stuff arriving at a system weeks before you get there yourself - anyone see any flaws in this? it trivialises the whole idea of space travel and the efforts it takes.
It needs to take realistic (in game) travel times, you plan ahead you arrange things to move off they trot, then for one reason or another you get waylaid - okay I'll get my combat ship back - whoa hold on there buddy this is part of a consignment and they'll end up where you sent them, then and only then can you arrange for them to come back - if they made their destination and that pirate gang hasn't taken out the transport ship.
It allows consequences and not just the case of who has the most money can flit here there and everywhere, maybe you are only allowed one transfer per month as there is a huge waiting list, bare in mind the AI will be doing likewise and there isn't an infinite amout of transporters.
These things need considering by FD it would actually enrich gameplay if the mechanic had a proper balance to it that has consequences.
imagine the storyline GalNet is reporting yet more losses of transported goods and ships between x and y systems - so far this cannot be pinned down to one faction or another - security escorts are now in place with the convoys as no transmissions or debris has been found from said lost transporters, bounty hunters are required to assist in escort duties in a relay fashion until we can isolate where the problem systems are. etc blah blah
