It takes the looooong web 2.0 funnels and flips it to a single step:
Your customers pay to interact with your app at all and there is insatiable demand at the beginning, unless you do some boomer-level system design that is based on pretending that a 3 trillion dollar crypto native audience doesnt exist already and you need to onboard a bunch of technophobes.
In comparison, the entire web 2.0 ethos basically sums up to getting a customer to put their credit card into your website for a small charge, as a funnel for a bigger recurring charge later
in web3 all of your users are at the last step at the very beginning. they are even paying for all your hosting costs. they are paying to update your database! and your actual business model of being some form of plumbing with a transaction fee, if you didnt just sell a token collection, is fine and has low overhead costs
this will continue attracting developers and their entire audience in perpetuity because the entire web 2.0 ecosystem cannot compete with that
