Yes, you are complaining. The fees aren't stupid high, they are set by you, the bidder, and can be set at will by you. If you elect not to bid, you elect to pay no fee. If you see a $100 item, and you pay $30, you pay $4.50 fee. If you think the fee should be $2.50, then bid $15. If you bid $100 on the $100 item, you then pay $15, and have exceeded the price of the item. But, you, the bidder set and accepted that cost.
What you are complaining about is that prices between a willing buyer and seller are higher than you would like to pay. Unfortunately, in an inflationary economy, particularly for very desirable items, we may not be able to buy things we want at the price we'd like to pay. Particularly if we want to buy them cheap and resell for our own profit.
If the prices are truly "too high", meaning that someone in the selling chain is making too high a profit, the buyers refraining from buying fixes that because the prices have to be dropped to make it sell. In an auction, that process is automatic, you stop bidding when the price reaches your threshold.
You are putting downward pressure on prices for the other buyers, by refraining from bidding, so the system is working to adjust the prices to market rate. As I said in my post, that's a success for the sellers and buyers, although it looks like a problem to the u-**** wannabe buyers.
Really, the TLDR version: You are complaining that someone else is willing to pay more for something than you. You are making the wise decision to just not buy. Kudos to you.
