Okay, lets look at just part of your reply.
"(If people have immunity for the regular old flu, why do they keep catching it and dying at an alarming rate, and why do we have to keep getting annual vaccinations?)"
My understanding is that some of us do have immunity for whatever the current strain or strains of the flu are. Some of us had it last time, and some of us had a minor reaction to it earlier. 1 month, 12 months, who cares, someone will have immunity to it. There will be enough people in society that have had it, that it will not spread as quickly if no one had it at all and no one had immunity to it.
Now, add in the people that get the flu vaccination and assume that the strains they used for the vaccine happen to match the dominant one this flu season.
Therefore we have a significant part of the population that are immune to the current flu. So the spread of this will be reduced purely because enough people will not be able to provide transmission.
Now compare it to Covid19 where no one has immunity, and it spreads between everyone that is exposed. Some will have minor symptoms, some will die. This ability to spread alone makes Covid19 more deadly than the regular flu if you assume that the viruses are equal in their ability to kill someone.
There's an article on news.com.au talking about Sweden and the death rate that they have seen from Covid19. You can try and dance around it and say its the same as the regular flu, but the numbers suggest something much different.
I must admit that if you are not trying to make out that this flu 'SARS-covid-2' is less deadly than the regular flu, then its true, I don't get your previous point.
I will go further and suggest that the 2 in the name means nothing of any substance just that its a related virus. It doesn't downplay the danger any.
Would you prefer a pandemic where you can easily screen people at airports and other locations with temperature scans, or one that doesn't always show up straight away as a fever? If that's not clear, SARS was detectable in most cases, whereas this time round this variant is not so detectable.
As always, if we can't argue the point over 'stuff', what's the point. Its only a forum for discussion...
"say its the same as the regular flu"
There you go again -- that's not what I have said or am saying now.
The seasonal flu infects millions, hospitalizes a couple of million and kill a half million or more people per year. PER YEAR.
Nobody freaks out, nobody locks down anything, it's tough to convince people annual vaccinations are necessary. People scoff at the flu. Probably explains why it's so widely spread, and despite its low R0 and CFR, why it takes out so many people ... because so many more people get it.
Compare that reaction to this version of SARS. See the difference? Aren't you puzzled by how indifferent people are to flu deaths, but wail and gnash teeth at the idea of reopening schools?
That's my point.
"immunity"
It wears off. The vaccines are best guess for what this season's mutations are going to be. It's an attempt to maintain a level of herd immunity so that it isn't spread as widely. And yet ... see above.
"no one has immunity"
How do you know? Having an infection without showing symptoms is common.

Not going there, too complex. CFR is low compared to the global rate...but.
"just that it's a related virus"
It doesn't downplay the danger, it highlights to the OP that this is not the first pandemic we've had in the last 20 years, and this isn't even the first version of SARS-covid, so the hyperbole isn't necessary. It's relative.
"Would you prefer"
You are forgetting about MERS, bird flu, swine flu... In our part of the world, we have a lot more issues with those and so have had temperature scanners at airports for decades. Relevance.
IIRC you're looking at that study with a very small number of people who were infectious were asymptomatic, and decided that it applies to everyone? That's just a faulty conclusion. See above.
But ... what's your point there?
