One of the solutions could be to reduce the STEEM's current inflation drastically to 2% from current 8.7% by eliminating rewardpool using STEEM.

Assuming that STEEM distribution has completed reasonably (better than ICOs such as EOS). New STEEM production will only be used for interest on staking and witness compensation.

Demand for STEEM will come from bandwidth purchases from the companies behind the SMTs, scarcity and speculation.

STINC, as a owner of Steemit will lunch their own SMT. Perhaps they can airdrop their SMTs on SP holders.

All the experimentation about rewardpool distribution on Steemit and other DApps will bottled out. These controversies will affect STEEM a little, since most are related how new rewards (STEEM) are earned.

The very DApp developers and community will decide on their own reward pool distribution for their SMT.

STEEM inflation will reduced severely, which will create scarcity, therefore, STEEM's demand will rise. Moreover, STEEM's valuation will also depend of DApps/SMT's success and DApp/SMT's bandwidth requirements.
