The invisible currency (edit)

[dukealien]

Loopholes weaved
around the process of greed
gradually perfected.

A web work so subtle
any rebuttal
was dissected.

Never a venture more costly
than the prevention of money
and it seems now
you've become greedy.

(Without looking at the other critiques up to now.)

First off, the subtle-rebuttal rhyme is delightful   .

A suggestion - perhaps the last line could be "you've gone greedy," or that might be too informal.  But it would be another short stanza-closing line.  On the other hand, the last line of S2 might be fattened up a bit.  Thinking "desiccated, dissected" or the like to amplify the spider (web) image of the stanza.

And now, at most basic, still, that first line.  To me, the past tense of "weave" is "wove" (in this case, "woven") - the other word "weave" that has a past tense of "weaved" involves zigzagging in motion - "he weaved back and forth, throwing off their aim" - where "wove" is obviously wrong.   Maybe it's transitive/intransitive.  But it's unfortunate, because you need "weaved" to rhyme L2.  I see no easy solution to the problem.

(Now to look above and see if anyone's found one!)
