I feel this token will cause a short term price increase in DEC and a long term voucher floor. Through burning both the get another token.

Long term it will decrease DEC price as it prints a token that reduces DEC deflation.

Why would we value a short term price increase more than longer term stability? I want this game to last years, kicking the can down the road is not the way to do this, I feel it will make the soft peg price difference bigger long term.

I will be voting no.

As other have said, allowing purchasing of land buildings now for a small discount (using DEC and/or vouchers) will achieve the same short term gains you are chasing without anywhere near as big long term costs.
