You're an optimistic but let me get you back to earth lol
1-There is no decentralized L2 and there won't be any time soon, unless the only guys capable of doing this decide to waste less time on core code and develop a truly decentralized L2 (you can screenshot this sentence as future proof).
2-Best solution was, when, if, there is a true L2, combine the rewards. As you know great part of active users and those who are coming soon brought by fundraising campaigns inspired by direct sales such as Herbalife or Tupperware are just here to get a job and pay bills, Hive would be a desert with just the usual camels if you simply take the rewards from L1.

Biggest Hive problems are visibility and better devs!

Tell me one guy with more than 100k followers on Twitter "you" onboard on Hive on the last 3 years.
Forget the rewards for a second and tell me one Hive dapp that you would recommend to your friends, be honest 😁.
