"You're still paying for an action, it's just an optional payment since it's not in the constraints block. You may use Luxurious Silk's Reaction.

In that case can it be used for action such as Peace and The Heir's Wrath?

Peace has no gold cost, and its ability reads: Limited: Search your Dynasty deck for a non-Unique Holding. Bring it into play (bowed), paying all costs.
The cost you must pay (underlined) is that of the holding, not of the action, so Luxurious Silk's Reaction may not be used.
The Heir's Wrath' s ability reads: Limited: Target another player's Personality, pay Gold equal to his unit's total Gold Cost, and discard the Imperial Favor or bow a Personality with five or more Force: Lose 2 Honor and destroy the target; these effects will not be negated.
Here, the cost you must pay (underlined) is equal to that of the target's unit, but it's a cost of the action, not of the target. so Luxurious Silk's Reaction may be used.
