| That's a bit cynical, I think. The address space has had a few "official" rationales because it serves a handful of duties at the same time; again, explaining a system is different than explaining a product, but pitching a system as a product is difficult. You often end up framing the system-as-product a specific way each time. > Urbit is a friendly network: a network on which you can assume that a stranger is nice until proven nasty. Friendliness is a direct consequence of scarce, individually owned identities. We're not changing human nature, just creating the right economic incentives. > Most forms of network abuse are "Sybil attacks": they rely on an infinite supply of fresh identities. Scarcity makes reputation work. Spam is a business; if the cost of a new planet exceeds the amount of money you can make by spamming from that planet until its reputation is trashed, there will be no spam. [1] While it's true an intent was selling the parts of the address space Tlon has to fund its development, its business model for consumers going forward isn't really to sell you planets; it's more about bootstrapping the project and offering hosting and support. For investors, purchasing address space (i.e. a galaxy or star within Tlon's ownership) is a way of investing in an asset that could be a source of income while also having some influence over how the network changes in the future, in the way a stockholder would a company. Essentially the address space is an attempt to create and maintain ideal incentives for the ICANN-esque players (galaxies), down to the ISP-esque players (stars) and the everyday user (planets), and their devices or additional users (moons) in a way that sustains the entire network.

Some lessons from neoliberalism are worth considering here. Sometimes people want to be fed trashy content. In those situations, planets offering trash will be popular enough to pay for the cost of (renting) the planet. (And make no mistake, rent and landlords are an inherent part of any real-estate offering!) So there will be spam, but it will look and taste like the offerings of Disney and Vicom, of Hasbro and Mattel, of Unilever and GSK.
Some lessons from other distributed systems are also worth considering. Technically, messages are always delivered by peers, despite the fact that the messages may have been composed by faraway unknown senders. This leads to local topological reasoning, and webs of trust based on peer-to-peer acquaintance. This can offer better performance and resiliency against attacks than Urbit's top-down neofeudal hierarchy of reputations.
I don't really want to support Tlon. If this is truly federated, then there ought not need be any corporate control over the system. History has shown that a few extremely ethical and competent hackers are more valuable in terms of software quality and usability than any sort of corporate planning.
I do appreciate that, by explicitly embracing blockchains, Urbit has demystified one part of its design: What makes Urbit property valuable? Only the hidden cryptographic keys at the base of Urbit's own signing system give any scarcity, and thus any value, to otherwise-uninteresting bitstrings. In other words, it's as valuable as ZCash or Bitcoin or any other digital gold; it's a Satoshi scheme.
