I am totally with you, AFAIK, however, Trust Wallet does not support a Layer 2 solution like Matic. The only thing that can be found in the context of Layer 2 and Trust Wallet is the (upcoming?) support of Immutable X for NFTs:
That's right, no layer2 on trust, so better OP transfer his fund to a metamask wallet cause using RPC network it can easily user the matic and fantom network and its totally a superb blockchain.
-snip-Unfortunately, this is also the disadvantage of the whole Layer 2 solutions ... the respective tool (in this case just Trust Wallet or also a Dex) must support these first ... and you have to pay a lot of initial fees to be able to "switch" to the layer 2 solution at all.
The latter is also the point why my (Shit-)Coins from 2017/2018 are frozen. A transfer of the coins would eat up about as much in fees as the coins are worth. I just hope that with all the measures such as EIP-1559, the fees will also become cheaper accordingly, so that the transfers are worthwhile again at some point. I don't need to switch them right now and can therefore still wait.
