Good thing is that you're not forced to use Liquid, so you can safely totally ignore it.

It will be good once Ark/Mercury get released and battle-tested. However even there you should be cognizant that these are not purely "trustless" solutions either.

For that matter, even in LN there are still trust issues - if you are not always online or hiring a watchtower your funds can be theoretically be stolen. Moreover you can also wind up without the ability to exit because of economic/fee reasons.

Again its all a series of tradeoffs.
