"I just try  not to worry about it too much and 
hope one day the companies can do something."

They can, though currently only ADV Films and 
Bandai have dedicated anti-piracy squads.  Bandai 
seized a whole ton of illicit Gundam gear at SDCC 
a few weeks ago, and were distributing flyers 
with the "we will take it if it's not legit" 
message at Otakon.  I am looking forward to ADV's 
domestic release of anime soundtracks, because it 
means they'll have the ammo to start seizing and 
destroying Ever Anime and SM crap.  Man, the 
amount of times I've wanted to walk through Anime 
Crash with a baseball bat...

Sadly, not enough companies are being as agressive 
as they should be--auctions of fansubs/vcds 
(including fansubs/vcds of stuff licensed and 
available in the US) turn up all the time, and a 
recent survey of eBay resulted in lots of "oh, 
whoop de doo, you live near a printing bureau" 
level of craptacular merch--badly printed 
t-shirts, coffee mugs, etc.  What's really awful 
is these icky, icky shirts I keep seeing in mall 
stores, these button-up ones with 
distorted/misprinted anime characters on 'em.  
Worst of it is misguided fans who think these are 
somehow legit or neat little things instead of 
what they really are: stolen property.  Just 
terrible, and I hope these crooks get shut down 
and fast for that kinda crap.
