I'm leaning against this; not because I think we need to hold on to people's stakes but because we have an inherent "structural" problem relating to how Steem is presented — and presents itself — to the world:

Everything here is always presented/marketed in terms of participating here in order to gain current income, rather than gaining from long term price appreciation. Well, if that's what we're telling people... then we're missing the mark on making long-term holding an attractive idea.

From reading all these comments, the closest to anything that makes sense is what Hive account@therealwolf offered... instead of penalizing people, or "locking up" their stakes, make it more attractive to commit to a long-term hold. Let's say (only an example) you hold for a year, you get the full inflation gain. Hold for 6 months, you get 75%. Hold for three months... you only get 50%. A month? 25%. And so forth... it's like any pension plan, medical savings plan, even investment plan... IT TAKES TIME TO VEST YOUR STAKE.

Psychology is important here... we may be talking about negligible amounts in terms of real money but people are very funny about "giving up" a higher guaranteed return... it's like losing something, and people hate to lose.
