You're right. Ross should have been granted a drug selling license, analogous to a liquor license, and it should have been revoked if he failed to check ID before allowing people to make purchases on his marketplace.

Teenagers routinely drink alcohol and sometimes die.

And businesses that knowingly sell alcohol to minors are charged with a crime.

Sure, but the crime isn’t murder. And they aren’t getting life for it.

If their business sold alcohol to as many teenagers as the Silk Road has sold drugs, then yes, they would get life.

Then why isn't the CEO of anheiser-busch given two consecutive life sentences plus 40 years?

AB-InBev does not sell directly to consumers. They have a distributor model of operation.

You mean how Silk Road didn’t actually sell anything but was only a marketplace?

Doing business in, or running, a marketplace without established legal regulations opens you up to undefined consequences. Without laws to bind you, there are no laws to protect you.

Do they get multiple life sentences?
