Probably like the difference between buying a Ferrari, a sea yacht, and your own private jet. A Ferrari is expensive to buy at first, but keeping it is relatively cheap: you need some garage space, insurance premiums, and some dedicated mechanic who knows what to do with your car.
A yacht needs marina space, which you have to keep paying for (unless you happen to own a sea-front house with a deep enough marina) and the upkeep of your yacht costs a lot of money. Fuel is expensive to keep running it and you must run the engine now and again. You must also run the air conditioning several times a month to ensure no mould grows there. You need to pay the crew. That's going to run you the cost of a Ferrari or two a month, just to keep it around.
A private jet may actually be cheaper to keep without using than a superyacht, but operating it is very expensive. Between airport fees, fuel (which you're spending a lot on because you're not flying around at the most economical cruising speed!), crew and other fees, each trip you take is going to be the cost of a couple of months of the superyacht's maintenance. And unlike the yacht, you don't usually live aboard the jet, so you'll probably also be paying for your mansion in Tuscany or Aspen.
So a fair number of people who could afford an intrasystem yacht couldn't afford a hyper-capable one. And some folks might not care about visiting other systems enough to want to spend the extra money even if they had it. Certainly from a system like Manticore if you want to leave the system there'd be no shortage of passenger berths you could take -- why buy the private jet if all you need is the occasional airline ticket?
Even if a first class ticket. Or, even, charter a luxury jet. It's very expensive to charter one, on the range of $100k/hour I think, but $1M isn't going to be even the downpayment on the private jet!
BTW, one of the ways Phil Knight from Nike pays for the upkeep of his jet (tail number N1KE) is that he "lets" the company use it, so the company pays for most of it. https://www.planespotters.net/photos/reg/N1KE
