Hi @Slickrick37 ,
From an economic standpoint, when currency is in reserve, or held off market, the market adjusts as if it did not exist (at least until it comes back on market). Removing currency from the market is one type of retractionary policy that fiat based soft monetary policy systems use in their central reserve system strategy to provide greater buying power within the supply of currency on market. Burning is one aspect that could be construed as retractionary, however it is not the only one. The main aspect of retraction is to contract the supply in circulation on market, to increase buying power that underlies the currency, and so staking also does this. It is true that unlike burning, staking can come back on market, but the market does have a 21 day notice while large staked amounts decide to leave a staking pool and are unbonding. There are other retraction policies that can be used to raise the underlying buying power of LUNA on one side of the base pool, or the currencies meant to mirror the real world currencies on the other side of the base pool, and the TerraSDR that tie them together.
In addition, if the currency meaning to be staked is not already in the form of LUNA v1, any swaps would be subject to the burn tax. In addition, any moves on to chain would be subject to the burn tax, and that portion would be burned and removed from the total supply as well as the total circulation.
This is not to advocate, or detract, from the views that have been shared surrounding 3568 in regards to the merits, but only meant to help clarify how staking is also an aspect that removes currency from circulation on market, and has the effect of removing it from the market.
I just wanted to point that out (although I know you specifically asked @ek826 ). He may also have some thoughts on this as well.
I hope you have a great day
