I'm just new in the crypto world but I would say that I didn't find high transaction fees issue for me. If you want your transaction get faster confirmation then its logical to pay high fees right? So I don't know why is people complaining about high transaction fees if you can control how much you want to pay the miners to include your transaction in a block.
The issue with the fees is that even if for you the transaction fee is not that big, you must understand that bitcoin need to work not only for those that live in the first world and that can afford 1 or 2 dollar fees, in a third world country that may mean a full day of work, so the issue needs to be solved somehow, and segwit may be a short term solution for that.
