I haven't checked how this is presented in 5E, but I remember in 2E that the costs of the stronger healing spells that operated on more than hit points, and especially the Raise Dead and Resurrection spells had a very high cost in material components, and took their toll on the caster. In other words, not to be used lightly and all the time. Which means finding someone to cast it for you would come at a correspondingly high cost.
In a well-designed campaign world, that should be reflected in either a high monetary cost for the casting of such spells (a church requesting a sizable donation, for example) or some kind of demonstration that the target is worthy in the eyes of the church or its god.
This can actually turn into a storytelling and role-playing opportunity. Imagine you're blind, and you and your party need to prove that you're a worthy person while blind before they'll restore your sight. Or the whole party is made totally blind for the duration of a test or short quest that you have to complete together before the restoration spell can be cast.
All this sufficiently explains the existence of blind people. Lack of imagination is not an excuse for bigotry.
Also, a character may be unable to get their sight restored, and that can and should be explored for its role-playing potential.
While the simple explanation that Klingons can get honor to mean whatever they want (see Worf's "discommendation" arc on TNG, for instance) holds some weight in explaining this, I like to think of Klingons as hunters, as much as warriors. When you hunt, you don't announce your presence to your prey. You hide until the moment when you pounce and attack. The cloak fits if you look at it this way, at least.
"In those days spirits were brave, the stakes were high, men were real men, women were real women and small furry creatures from Alpha Centauri were real small furry creatures from Alpha Centauri."
Isn't that covered by other laws, though? "Impersonating the government" or the like? I feel like a warning about breaking that law would carry as much weight as a copyright notice.
As for your point about "so long as you're not selling it", I feel like there must be a better mechanism than copyright... Government information should be owned by the population itself, and should have its own laws, separate from copyright, but I don't know if any such examples.
You owe it to yourself to try Strange New Worlds. It's just really good. It avoids most of the problems that Disco had (though it got better after season 1) and goes back to the episodic feel of past series, but without the ridiculous reset button that some series suffered from.
Familiarity with TOS will provide you with extra enjoyment, but it's not a requirement, in my opinion.
IQ has very little to do with this. There are some very intelligent people who are also very religious.
A lot of people confuse intelligence with wisdom. If you considered a human mind like a computer, intelligence would correspond to the CPU and RAM, which determine how fast you think and how much memory you have (and how good it is) whereas wisdom is like the software that runs on the computer.
Install shitty software, and the most powerful, fastest computer will just give you shit. Garbage in, garbage out, as they say.
You take a guy like Elon Musk, for example. Clearly intelligent. Definitely not slow. But he's spectacularly wrong about many things. Because he was not taught right when he was a kid, and he then learned the wrong lessons in life afterwards. Bad software, bad data. Still very intelligent.
I think it would work even better with the third frame showing Miles looking off to the right, with no dialogue... You know, show, don't tell, that sort of thing.
Nimoy was a very funny guy! Great comedy instincts! You get another tiny glimpse of it with Spock's line "I've been dead before" in ST:VI. It's almost a throwaway, and said without emotion, but it's pretty funny!
Some good examples here. I'd just mention a few other memorable dialogue scenes:
all the scenes of McCoy with Spock's Katra in ST:III, including lines like "Yes, Genesis! How can you be deaf with ears like that?" and "Where's the logic in offering me a ride home, you idiot? If I wanted a ride home, would I be trying to charter a space flight?"
in Star Trek IV, the scene with Kirk and Spock in Gillian's pickup, with Nimoy doing his best Gracie Allen impression. Also, the "No dipshit" bit in the restaurant.
I don't know if it's my favorite, but A Day in the Life by The Beatles is quite a ride.
