... there will never be enough STEEM for many accounts. in 15 years from now and based on the current code which could change, there will only be double the STEEM in the supply and, there will only be around 6 million more added each year through inflation. That is not enough for a hundred million accounts as each account could only have a max of 6 STEEM.

A hundred million accounts? I would take just a couple million of active ones at this point. Besides, they can always ratchet down the RC requirements if needed. Not having enough steem is basically the last thing I would be concerned about at this point. We are more likely to die and whither away than we are to ever have "too many people", especially with people running people off of here like it's fun for them.
Even with your 2 million active accounts (provided my proportionsl math is right) there would still only be 300 STEEM per account as opposed to 6 with 100,000,000 accounts. Not even enough to make minnow. Buy while supplies last! 😎
That is not a problem. That would be a feature!
But I digress, we are so far away from that ever being a problem, I will worry about it then.
we can scale steem with a third payer solution like @liquidapps https://liquidapps.io does for eos and eth, and ive already asked them about adding steem, and getting steem on scatter and newdex adding SMts.
