Only if that’s all you have is larger UTXOs. The con to that would be that in the future when you would want to spend it, you’d be showing the merchant how large of a UTXO you have. It’d be like buying a candy bar at the corner store while flashing the cashier your wallet full of $100 bills…probably not the smartest thing to do.

Is this even a concern? It feels like any transactions like that in the future are going to be L2 transactions? I don't see L1 being used for anything but opening channels and extremely large transactions.
