I totally get your point and agree, overall.
But let me speculate a little bit.
Right now market cap for VOUCHER is around 500k$ and for DEC is 3.5M$. There are 150k plot trading at 118$ each.. so roughly land plots have a 17M$ market cap. We can assume each land owner will have to spend 50% of plot value in buildings and upgrades.. and that 50% of that will be burned tokens (total speculation here, just to have a hint of the order of magnitude involved). There are out there millions of $ of potential sinks.
I think DEC-B is all about timing. Sinks will be available during 2023 but if economy twists earlier is better for everyone.
I think some sink will require VOUCHER and other DEC. So i would have preferred introducing DEC-B and VOUCHER-B... keeping stuffs separated. But people don't want new tokens.. so I understand this semplifacation and aggregation.
