Also to be fair, is it proven that Tor's most popular use-case is something other than criminal activity? I know there are legit uses for Tor certainly, but it wouldn't really surprise me if criminals were the primary users

Criminals are numerically the most common Tor users. But the difference is that what's "criminal" depends on your place of residence.

In America Tor is mostly used (other than as a curiosity) for drugs and child porn. The former I could care less about, while the latter is indeed creepy. It's also occasionally used for private communication with journalists, a numerically less common use but a politically critical one. While I strongly detest child porn, I equally detest drug prohibition and journalist and whistleblower harassment/censorship.

In Iran? China? Saudi Arabia? Russia? In places like that Tor is used for dissident communication and private correspondence with people overseas. In those places public opposition to the ruling regime can itself be a crime.

There are also authorities including police and intelligence personnel who use Tor -- very ironically to hide from criminals. For example, an undercover cop might use Tor to hide their correspondence with the police from digital snoops in the employ of a criminal organization they are infiltrating. Some organized crime outfits are very sophisticated, making undercover work actually require a degree of 'op-sec' on the part of the agent. Compromise can be fatal.

Tor is a gun. Criminals use guns but so do police, hunters, and people legitimately defending themselves. In America you could probably defend Tor and other crypto tools on second amendment grounds.

Please provide sources to support your argument.

Edit: Why would I be modded down for asking someone making claims (questionable ones at best) to provide sources?

Try this:

"... First, the pedo site saw magnitudes more traffic than the counterfeiting or drugs websites – in the order of 100 times more traffic than the other two combined. ..."

BTW I wasn't arguing that Tor itself is bad, just refusing to engage in the common denialism one sees among crypto and Tor advocates in claiming it has no bad uses. The truth is that many things have negative uses: guns, knives, security systems, Bitcoin, crypto, fireworks, spray paint, alcohol or virtually any drug, explosives, drones, cameras, etc. All those things have positive uses as well, and it's ultimately the user who is responsible for how they are used. Pedophiles use SSL too, should we ban that?

As far as police and intelligence agency use of Tor, look up some of the talks by the Tor founders in which they cite examples of these uses. In addition to undercover use, Tor is useful for law enforcement to hide their network location while investigating potential criminal sites online. Otherwise a site might easily see that the traffic is coming from a police or .gov site.

Traffic to hidden services makes up a tiny fraction of the overall use of the Tor network.[0] Any conclusions drawn from that use is highly skewed, and cannot be used to draw conclusions about Tor itself.

Rarely is the law interested in something like "most popular use case", or a mere plurality. There are different standards for different circumstances, but usually it's something like substantial noninfringing uses, like in Sony's famous Betamax case.

This example is from left field, but the reason I bring it up is that no court will want to know what a plurality of Tor users do with Tor. The standard is probably much lower than that.

Given this, what is probably more interesting is to catalogue different legitimate use cases for Tor. Then cite actual examples of real people using Tor in these fashions, and how their freedoms would be infringed if they could not use Tor.

For example, I use Tor regularly to see how web pages render for people other than myself. It allows me to check how personalized a website has been made for me. Especially with ads, if I want to guess at how targetted ads are to me, I can use Tor for comparison.

I don't know the answer to your question, but one thing to keep in mind is that "criminal activity" does not always imply "morally questionable activity". To use extreme examples, someone watching child pornography isn't the same as a journalist hiding from an oppressive regime.

Here are the stats by country. I don't think there any more detailed stats available, as not tracking is the whole point of tor: https://metrics.torproject.org/userstats-relay-table.html

  Country 	 Mean daily users
  United States 370492 (18.53 %)
  Germany  	 201280 (10.06 %)
  Russia  	 173453 (8.67 %)
  France         125916 (6.30 %)
  United Kingdom  87386 (4.37 %)
  Brazil  	  64918 (3.25 %)
  Spain  	  62547 (3.13 %)
  Italy  	  60229 (3.01 %)
  Japan  	  50234 (2.51 %)
  Poland  	  41437 (2.07 %)

You can draw your own conclusions from that :)

What could possibly be done with a communications relay that would fall outside of this proscription?

Unless you just mean "criminal" in the age old non-rule-of-law sense, people who are shunned by society.
