I believe 1 satoshi/byte is the lowest fee/unit to use.
well we used to be able to send with 0 fee

but those days is over, I think all miners only accept min 1s/B fee now.
If we ever go to 100% (or anything near it) and fees reach their minimum, why there would be any need for Schnorr, Bulletproofs or any other proposal that could decrease transactions size?
Because it won't stay that way and the transaction count that needs to be handled is only going to grow.
I think instead of coming up with the negatives we must think about positives. With fees going down to 1sat/byte I think the scaling problems will almost disappear for once.
the scaling problems will never disappear as easy as that.
I agree with
HeRetiK the transaction counts will only grow with time
it just that in time like this, for whatever reasons there are only small number of transactions being made
the more users joining the network, the more bitcoin adoptions, the more frequent users make payments and so on
thus more transactions will be made... therefore the scaling problems will always exist when bitcoin usage increases
"If we ever go to 100% (or anything near it) and fees reach their minimum"when we are at 100% segwit txs, min fees reached and low tx counts, that means the network is at lowest level of scaling problems
what happen if 100% segwit transactions but the number of transactions multiplied 10x times
because there 5x new users and each make 2 transactions constantly every day? network load will increase drastically!
then there will be competition for transactions inclusion in block followed by increase of transaction fee
you need to take in the # of transactions and bitcoin popularity when talking about scaling problems
