If "try again!" always was silly coding practice, the the concept of "busy waiting" would not be known. Busy waiting does have its place, especially in embedded systems where the processor has nothing else to do.
Another situation is where several activities are competing for the same resource, but they hold the resource comparatively briefly. As long as you can modify all the competitors, you could program the queueing mechanism, where a process trying to access a busy resource is sent to sleep in a queue and woken up when it gets its turn. Often you can only modify some of the competitors. The effort of implementing a queue mechanism may be high. If the risk of collision is small, it simply doesn't pay.
I have fairly recently programmed a couple "try again" cases: On a quite heavily loaded file system, the number of exceptions due to confliciting accesses was higher than desired. So, when making modifications to a set of files, I make one try for each. Those failing are put into a list for retrying, and a second attempt is made once the first round was completed. Only after a second try, the user is notified. We went from too many access collisions to almost none. Sometimes, the second try came too fast, and the file was still busy. So I added a 5 ms sleep before starting a second round, and after that I haven't seen a single collision.
This "try again" code is next to trivial, and it does solve a real problem. So I cannot agree that the strategy is silly in every case. Sometimes it makes perfect sense.

 Great examples but not quite the same as the OP where it doesn't make sense to try the same command again right away.
This also brought to mind a program I have to migrate database objects...those having a dependency yet to be created fail and get put into a recursive 'try again' queue.

So, you just assumed that whoever/whatever else had been writing to the file had been doing nothing worthwhile? Personally, if I detect any changes to a file I would avoid writing to it, and notify the user. Better still, open it for exclusive write.

I have a few SQL scripts as embedded resources in my app, for EF seeding. To make sure other coders, or me much later, don't go looking for these scripts, I added the following comment to the first line of each one:
-- This file is used as an embedded resource and not included in the build output.
Then I build a little ResourceManager that for now just reads embedded files, and when I tried it out:
var script = ResourceManager.ReadEmbeddedTextFile("SeedIdTypes.sql");
and hovered over the script destination var, I never saw past the comment, which I had forgotten about, saying This file is used as an embedded resource and not included in the build output, and I assumed it was the CLR complaining about my build settings for the script file. A wasted half hour later, I looked closer, and saw the SQL, realised the script was being read, and the "error message" was my own comment.

That's what happens when you create professional looking comments. If you'd written "hey, dumb*ss, you can't do this!" you would have figured it out right away!

I have been bitten in the rear with similar comments. Now I sign my comments with my initials and data. An added benefit, I can search for my comments.

I used to do exactly the same, but I so seldom work on shared code-based these days, it's all my own, so that sort of ell by the wayside.
Except I used to put the [BK 20170418] first, so it's always in the same left side of the sreen, regardless of comment length.

Everything is more simpler. Words and more words but reason does not matter. How to distinguish truth in an ocean of false information? How to find the best path for everyone if nobody cares and everyone accelerates? How will we know the truth if we ask for evidence that is impossible to obtain?
