There is enough depth in perpetuals, not only on Kollider. And of course, users shouldn't use fiat-denominated liquidity for store their wealth there. 

And Fiat Channels may work with bearer stables as well.

Sure, also USDC can freeze addresses by government request. But few people care.

The key word here is "synthetic", in other words, this asset is an algorithmic stablecoin less battle tested than Terra. The problem is you can't synthesize more value than the underlying asset (bitcoin) has. For example, suppose people send 10M$ worth of BTC into Kollider and mint synthetic $ with it, but then BTC goes down 10x. Is there 10M$ value still in the $ tokens? Of course not. This is when you activate HODL mode for everybody.

Taro will allow normal non-synthetic tokens like USDC and USDT to circulate on LN. That is the way.
