 If your immediate goal is to get a UTXO for longer term storage then sure. The reason I say LN first is because of the default level sender privacy.

 And it allows you to accumulate a larger balance off chain, before converting into a UTXO.

UTXOs <1m may well become economically unviable in the future

 Utxos <1m may also be combined when forming a txn and one can combine dust outputs together if they all belong to one entity if possible.
Why so much myth about” will be economically unviable”. 
Just like I can combine a penny with a dime or a quarter and then add that sum and spend it. I can do the same with utxo and  burn some of that dust on miner fees. Or use that utxo dust as a Payjoin when receiving.

 Its not a myth. Small utxos become economically useless in high fee environments. Of course you can combine them, but doing so may cost more in fees than the value of the coins themselves.

 Sure, but when I combine or consolidate I will use/ burn those dust utxos into fees instead, sure it cost more but it’s spendable. goal is to get rid of the dust as part of miner fees. I still don’t buy this bullshit that one need to have 1mil size utxo or bigger now as a minimum total bullshit.

 It's not really 'spendable' though is it? You're losing more than the value of the coin itself. That's the entire point.

▲ ▼

 Even if you combine them, you might end up paying more for adding another utxo to the transaction than what that particular utxo is worth.

In meat space it's not more expensive to add 10 $1 bills together than spending 1 $10 dollar bill.

But in bitcoin land adding a new utxo increases the size of the transaction therefore increasing the total fees for that transaction. There will be a fee level at which certain utxos will be more expensive to send even if added to a transaction with more utxos

 FWIW You’re making an argument against yourself
