Can some explain to me why fees will continue to rise in terms of total sats if the price of Bitcoin goes up? 

I get why it will never be 1 sat per byte again if it gets more use.

But when Bitcoin is 2 million per coin, the price in total sats to settle on chain could be less or more depending on demand. 

So wouldn't your 100k sat UTXO be fine?  It will still cost more in fiat terms but total sats should be less of Bitcoin is worth more?

Am I crazy?
