F-M,
Are you claiming that bricked up windows are evidence of the etymology of the phrase ?
(They're certainly evidence of the effect of the law.)
Why can't "daylight robbery" be the opposite of Burglary as defined in UK Law ? (entering with intent to commit a felony at night).
Or just a robbery committed in daylight (so all can see) ?
Occam's Razor and all that.
