My brief answer is that we already have under-used tools to do this:
- moderators can delete questions,
- some users can vote to delete questions (and that now includes you),
- more users can vote to close questions,
- many more users can downvote questions, and
- the Roomba does the rest.
This is the long answer:
Within our site the only option we have to customize the Close Reasons is in the Off-topic section (below) where we are restricted to being able to specify the top three. We only do this after careful consultation with the community like we did at at Improving wording of "non-reproducible" custom close reason? (I often use this rather than deleting to deal with questions like those concerning you).
In theory we could swap out one of these but I could not see a "immediate deletion, pointless question" alternative being supported by the community.
By going outside the community to the network-wide Meta Stack Exchange you could try to get an additional close reason added to the first close menu (below).
However, I do not think that this would be successful either, and unsuccessful feature requests there can receive a lot of downvotes, so I recommend caution if you take that path.
Personally, I think we currently have the tools to deal with the very real problem that you have identified, but I think those tools are being under-used by those within our community with the privileges to use them.
- The seven elected moderators can instantly delete questions, which we sometimes do, but that is exercised rarely (answers are deleted much more often).
- We currently have 42 non-moderator Trusted Users (20,000+ rep; includes you) who can vote to delete questions.
- We have 398 users with the Cast Close and Re-open Votes privilege (3,000+ rep).
- We also have 12,924 users with the Cast Downvote privilege (125+ rep).
It is this last group who can help to make a big difference because when they downvote questions (which costs no reputation; downvoting answers costs 1 rep) they nudge the questions that are concerning you here into the path of the Roomba which can auto-delete them. To learn more about the Roomba see the accepted answer to Turbocharging the Roomba: solutions for premature deletion.
Something to be aware of is that every time an upvote is placed on a question like the ones you are wanting to delete, which I think some users may do out of sympathy, it makes it harder for the Roomba to do its job.
Some recommended reading, that shows there are even more ways that questions can be deleted than those I have listed above, can be found at How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?
