I think that you did an excellent job of doing so yourself. In brief: . criminal prosecution is on the taxpayer's dime . awards for civil damages have to be collected, which entails locating hidden assets (which is itself and expensive and difficult proposition). All too often, a good deal of the assets went up the bad guy's nose.
Simply put, you greatly underestimate the magnitude of the task.
The task of updating software on commodity PCs (which you refer to) is nothing compared to that of updating other clients, much less the servers. There's a whole world out there that you're apparently unaware exists, and not even Microsoft controls it.
Furthermore, commodity software updates do not depend upon updates from other vendors. It would take many years (and I do mean *years*) for all of the vendors involved to agree upon the new design, new protocols, and set an update program in motion.
Just take a look at how long IPv6 has taken, and is likely to continue to take.
I am not trying to discourage you from this plan. It would be foolish for me to do so, as you are effectively waving around a huge chunk of pork that will have people like me on a feeding frenzy for years to come. I'll be retired long before it's ever deployed, so that I won't to worry about fixing the mistakes that will inevitably be made.
If you are deterred, don't fall into the opposite trap of despair and saying "nothing can be done". Individuals, organizations, and governments are still actively applying band-aids to the spam problem. None of these will completely solve the problem, but presently the economics of spamming will cease to be as attractive and most spammers will move on.
And who knows, maybe some day whomever ends up managing the Internet will be foolish^H^H^H^H^H^H^Hfarsighted enough to commission a complete redesign of Internet email. It would be a nice sinecure for me and lots of other people.
This is all true. Nevertheless, you misunderstand the purpose of email postage stamps. It is not for infrastructure cost recovery; you pay for that in your ISP fees.
Rather, email postage stamps are a *tax*. The ostensible purpose of the tax would be to pay the government to provide the service of policing email. As with other taxes, the services provided and the amount of the taxes you pay will be decided by the government.
As with other taxes, you can bet that when the money starts flowing, there will be taps put on that flow for other purposes. The Spanish-American War effort was paid off a long time ago, but we all still pay the federal excise tax on telephones that was established to pay it.
Mind you, I personally favor the imposition of email postage stamps! But my reasons are not the same as yours, and you would not like my reasons.
You ain't seen nothin' yet.
Crooks have nothing on governments when it comes to the bite.
Do you buy products from catalogs that you receive unsolicited in the mail? Why or why not?
