Useful legal analogy re Internet versus other "legal" gambling

[erac22]

if the issue is money laundering, why not just stop all money transfers on sites? How could money be laundered if the only option was to send money from your bank account, to your online gamlbing account, then back to your bank account? The site I play on doesn't allow transfers, and I have no problem with this. It actually makes it more hacker proof and more secure. Surely this would solve the laundering problem, wouldn't it?

**I guess people could chip dump, but it seems that sites have software detection abilities to prevent this?
