Assume it was 1-click and 100% automated to deploy, run and update a Hub.

How much per month would you be willing to pay to run one? 

No direct economic incentive other than you know you're supporting Farcaster decentralization and you have your own copy of the network.

OK, if you're answer is you wouldn't run one.

$100 per month seems reasonable for a crypto dev who‘s prototyping a new app. But make it easy to cancel and use “virtual cards” like privacy.com.

$10 per month for a student.

Oh also, you should probably charge break even amounts here. Devs will make Farcaster more valuable. So charge the minimum to not lose money on the hosting costs.

Break even amount for sure. I think as an individual, parity with Twitter/X pricing would probably result in most signups
