This sounds defensive :P

Why not support Steem now?

That was not the question: why not support it on Steem now?
It was about the changes in the curve, DV pool etc...

There is nothing wrong with this idea you put forward, it is that it doesn't offer much that can't be done on Steem already other than the large staked 4. When it comes to that stake going to a funding pool, it then has to have value which means it takes time also. Once it has value, it needs to be sold. Who in the community would want to have it dumped at the highs? one of the criticisms of Stinc was not dumping the stake at the highs to fund the lows but if they had, who would have been happy as it would have brought the price down even faster and all those who did sell, would have made less?

This idea can be done quite easily with soe devs who recalculate the pool and distribute to the posts on Steem as they are now with the new token. On some platforms, that token will be the only one used. If it gains in popularity and demand and people don't dump it, it should build in value until that large pool part has value too and can be used for onboarding and marketing etc. This all takes time also and I am not sure if it would be much faster than another 3 years. Worth the attempt though but unless the economics is quite different, it will still have the same community with the same habits and likely, the same issues.
