Let's say an attacker wants to use/exhaust the network's bandwidth, and has the choice between renting resources from a commercial provider and getting the network to "spam" itself it by sending unconfirmed transactions. We'd like the latter to be more expensive than the former. The bandwidth for relaying a transaction across the network is roughly its serialized size (plus relay overhead) x number of nodes. A 1000vB transaction is 1000-4000B serialized. With 100k nodes, that's 0.1-0.4GB If the going rate for commercial services is 10c/GB, that's like 1-4c per kvB of transaction data, so a 1000vB transaction should pay at least $0.04. At a price of 120k USD/BTC, 100sat is about $0.12. This price allows us to tolerate a large decrease in the conversion rate or increase in the number of nodes.
