Good analogy
I nearly missed the KS campaign and only got on board a month before the end but backed as much as I could, remembering all the summer holidays and time I spent playing on Elite back in the day
I personally feel when people backed on KS early they were putting their faith in DB and FD's ideas, skills, vision and hard work. With little or no information available, no videos around on youtube, and did not know whether the game would be even made, let alone what it would be like (X anyone?), it was their risk. So by taking that leap of faith and backing at that point, the rewards for that risk should not be repeated, nor the benefits be available for people backing later and knowing what they are putting their money behind. When FD made Alpha and Beta available in the shop once the KS period was over, people backing from then still get early access, and as we know more recently the 1/2 price ship insurance for Alpha backers... these are the rewards for backing E: D later.
Its a shame people didn't know or couldn't get on board at the KS time, but if you arrive at the station late, expect to miss the train
Saying that, it may be of interest for people who missed the KS period to know there is a thread elsewhere in the General Forum posted during that time discussing what starter ships & locations people would take. It turned out from the poll that most would be taking the starter Sidewinder and 100cr option regardless of how much they backed or 'could' start with! So all those KS rewards - at least for people's main characters - would not even be used. If you consider and think about it, by starting with more than the basic loadout and credits, many felt this would lessen the 'Elite' accomplishment in the long run
I know a fair few (myself included) even want to start in the Founder's World to have a good nose around, but then start again in a normal starter system. Admittedly I'd probably use the benefits on my second and third characters but, for the first, Sidewinder and 100cr all the way
