Our own past (say, 1974, for example) is also “separated from us not by a space-like frontier, but a time-like one“. Would you say that the past is not real?

The frontier I was talking about is impassable. It's "infinitely in the future", aka "never". That's a whole different level of frontier, imho.
Granted, there is a bit of tree falling[1] conundrum here, but that does not make the question less interesting (arguably, it even makes it all the more so).
