What's the story behind this character 盗? None of the components seems to hint at the sound, or the meaning of 'pirate/steal/rob', unless water in the upper left part and is the bottom component a corrupted version of boat 舟?
「盗」 is Simplified Chinese, the orthodox character is 「盜」.
「盜」, to hold selfish desires towards material goods. From semantic 「㳄」 (drool > to covet), 「㳄」 is that who wishes for 「皿」 (dishes/bowls)*.
*The ancient middle-upper classes often had expensive bronze vessels, so these are a sign of material wealth.
To covet material goods was then extended to to steal. In fact, this isn't too far off from how the glyph origin of 「羨」 (envy) is described - from semantic 「㳄」 (drool > to covet) and semantic 「羊」 (sheep), indicating the original meaning the desire for mutton.
If one wants to trace 「盜」 back to oracle bone script, it is usually explained as
starting off from semantic 「㳄」 (picture of a person with an open mouth with spit coming out > to flood, overflow) and semantic 「舟」 (boat), indicating the meaning flooding (of a river).
「㳄」 was later complexified into 「𣶙」 through the addition of another 「水」, and 「舟」 was corrupted into 「皿」.
These forms are thought to be pronounced similar to 「㳄・涎」 or 「羨」. How this then becomes the meaning and/or sound of 「盜」 is then a bit of a leap.
