If you want an example of how an askew chainline can upset things, get going on a poorly aligned fixed gear. A thrown chain will happen.
And your persuasion on using 53-25 on a double hinges on chain length -- if it's OK, you generally haven't got an issue.
A single speed chain does not flex when misaligned. A single-speed must be aligned perfectly. It's apples and oranges, the two have little in common.
