My two cents:
Surely the base insentive here is to reward the most stable/reliable BPN nodes, always online always processing transactions - without fail. If you have a flaky connection or are about to move house I would suggest you set up some proper infrastructure to host your BPN (Amazon, Azure etc...) The amount of money you can make from running a BPN will/could well go above and beyond a hobbyist crypto-staker and as such it would be inappropriate or unrealistic to think you could casually just run it on your old laptop whilst making a small fortune. - Aside from up-time and high reliability what about security? (physical and digital), what about backup and disaster recovery? - when the money gets serious the old laptop in the cupboard approach will not do, some bitcoin mines have diesel generators on standby and even employ guards to protect their assets!
If running a BPN is not for you then feel free to stake, it's not as profitable however its still free money

I like the idea of a limited queue, it fosters competition to "be the best", you deploy the most stable/reliable infrastructure you can muster and wait your turn, it might take a few months to grab a place in the queue but if it takes 4-8 months to be in a position to make thousands a day for basically doing nothing then I think I can wait...

Mostly true but if it did take months?? (in crypto that is akin to decades) would you actually park you coins there and get nothing in return whilst you wait?
If you would that is cool. Not sure many would though.
We can try it and see. However like you say if it ever becomes worth 1000's per day to have a MN then most will make sure they do have the reliability to retain a MN and you could be waiting a very long time indeed.
I would think the queue should earn at the very least 50% stakers rate.
