You're wrong with "apparently not". Yes, it would cost money. But if your only concern is cost you might as well not even build the line at all. That would be even cheaper. What's the point of doing something half-assed and spending many millions of dollars to provide such a poor service. Apparently it's every 10 minutes now. That's a little better.
To someone having to put up with a long wait because they just missed the last streetcar, they don't justify it in their mind because it would be more expensive to run it more frequently. They just know that it's inconvenient. I'm quite surprised that someone would defend such a poor level of service (I'm talking about the 15 minute headways, not the 10 it's apparently running at now).

To shorten headways to half what it is now, to 7.5 minutes, you'll need to operate twice as many trams. That's twice the costs. To maintain the subsidy as is, you'll need twice the riders paying the same fares. But are the streetcars overcrowded today, is there a latent demand for twice the seats? I suggest not.

Demand is not fixed. The more frequent a transit line's service, and the faster a transit line's service, the higher the demand will be. There are thousands of people working and/or living within a 5-minute walk of the line from Denny Way north (which is about the point the area is no longer easily "walkable" from the south end of the line where it meets the transit tunnel, where most people would be starting the trip in the morning if they took transit). The fact that it only does 2400 boardings a day suggests only about 1000 people (max) are using it to get to work and back daily. So the demand obviously isn't high. But that is expected given the relatively poor service levels.

But since they did use this simple and cheaper track arrangement, it also reduces the number of trams idling at the end stations in half. If it takes 5 minutes elapse time to turnaround the trams, with perfection of operating, the most trams you can have on this route is 6, with precisely 5 minute headways.

Every 5 minutes would be pretty good IMO. Every 10 or 15 minutes is not. At least it wouldn't be to me. Maybe you're more patient and don't mind standing around waiting.

And what is the best headways for streetcars? Shouldn't each line be addressed individually?

Sure each line should be addressed individually. But I don't see why any line should run every 15 minutes. That is just not convenient.
The line I took to and from work every day runs approximately every 2 minutes from about 7:30am to about 9pm. Even at 1am it's still running every 6 minutes. You can see the schedule here:

It's great. It was frequent enough that if I wanted to go to lunch somewhere more than half a mile from my work and didn't feel like walking, I could take the line to lunch, have plenty of time to eat, and take it back to work, knowing that I'd never have to wait long even though it was midday and not peak hour. It's also nice know you're not going to have to be standing outside waiting too long in the middle of winter.

Dallas is building an entirely single track dedicated lane streetcar line less than 2 miles in length with 20 minute peak headways running on just one tram.

Sounds like a complete waste of money to me. At least until they start running it more frequently.
