I think the author implied both more money and more foresight on keeping the ship design simple.

It plays well into the narrative though, Moitesser was much older and better funded which gave him the ability to presolve a lot of the problems.

Knox-Johnston had to make do with whatever he could from the onset.

I read it as you can spend time/money to store "maintenance capital" such that whenever you need it you have payed for it in advance or you can pay as you go... With the risks and uncertainty that comes with it.

What you cannot do is borrow technical maintenance indefinitely, sooner or later you must pay up.
