Nikon is going to have to talk pretty hard to capture the new beginner that wants to get into ILC photo gear. I just saw a local Walmart ad and they have Canon R100 with kit zoom for $397. And once someone gets started with brand x, it's twice as hard to get them to upgrade to a different brand. And I don't think Nikon is in a position to match this.
Yes, as limited as the the R100 is, pricing the kit at under $400 is lot more attractive for new users than the Z30 kit at $699.
Where does Nikon really expect to get new "recruits" these days?
It is true that there is a significant tendency for photographers to stick with the brand that they begin with. But it's not written in stone -- millions upon millions of photographers switch brands, or add a second brand, once or even multiple times in their lives. I myself own 4 digital camera brands, and 2 film camera brands.
In the 1950s and 1960s, and even much of the 1970s, Nikon either did not make entry-level cameras at all, or made a negligible effort in that market segment, even as competitors like Pentax, Miranda, Minolta, Ricoh, Petri et. al. sold tons of cheaper cameras to beginners.
Instead, Nikon's strategy was to capture a significant number of the photographers who became serious enthusiasts, and get them to switch as they advanced in their photography. The number who transition from entry-level to enthusiast is, of course, low in percentage terms, but they spend way, way more on camera gear than entry-level buyers do, so they are much more valuable customers.
This strategy worked fine; Nikon was never the unit sales leader in those decades but had a quite respectable value share (i.e. share of dollars spent) and was very profitable. They got a lot of switchers. Many other companies have pursued a similar capture-switchers-as-they-advance strategy and succeeded with it (Hasselblad, in the medium format tier, is a prime example). The key to this strategy is your brand reputation -- you have to be seen as a higher quality choice. That's Nikon's biggest challenge now; it was easy for them in the 50s and 60s because they started out way ahead in prestige and technological capability (primarily optically).
Now, you can also be quite successful selling tons of entry-level cameras and, for that small percentage of people who become enthusiasts, giving them reasons to stay with your brand. Canon, starting in the 1970s, is the prime example of that.
So both strategies have their merits, and companies can be highly successful either way (or somewhere in between). But not competing much or at all in the entry-level and then targeting switchers as they grow into enthusiasts (from entry-level ILC cameras or from smartphones) can work fine. Nikon has reverted to a strategy that worked quite well for them for decades.
