If it really comes down to it, I wouldn't be surprised at all if the Reddit admins just kick out all the protesting mods, finding replacements will likely be pretty easy.
Edit: Mass removal is already happening. https://news.ycombinator.com/item?id=36412619
The mods of several large subreddits were all kicked out, leaving the subreddits unmoderated. Multiple of these removed mods are also locked out of their accounts.

If there's a market for paying users directly for content, and also as a way to not need mods, someday this market will bubble up.
If you pay people in power, as they do, people will put their heart and soul into it. Not everything is a monetary transaction, and there are better incentives.
Giving money to mods won't help their IPO roadshow or make them profitable.
