My thoughts are that the totality of the subjects she addresses (i.e. the ones you list) cannot be properly understood from the worldview we currently hold as 21st Century Westerners. First of all, in order to travel from distance planets, or even to exist in hidden regions of our own planetary sphere, "extraterrestrials" would need to violate many of the laws of physics as we understand them. This makes them indistinguishable from so-called interdimensional beings, which in turn cannot be distinguished from jinn/fae, spirits, demons, etc. Throw in the weird liminal region between extraterrestrial phenomena and occult evocation practices and you open up even more questions about our worldview vis-a-vis time and space.

To address all this, as well as some of the topics we have been exploring at the old hangout, I think we need to come to terms with what I am starting to call the eternal now. Time itself is an illusion set up by some of the very "alien" beings that are the subject of Linda Moulton Howe's work. It may very well be the case that the concept of "extraterrestrial" is merely a projection of our own limited understanding of how the metaverse really works, and is not tangibly "real" in the sense that we generally take for granted.

Accounting for all that, well, yes, I agree with many of the things she says. But I understand them differently because of my acceptance (though limited understanding) of the eternal now.
