1. The lack of authority from the crypto founder to resolve issues from its user.
Which is exactly why cryptos are popular. The fact that each user holds the power to choose what they want and not have a "government" or someone holding the control of the system and make decisions that could be undesirable or unpopular is why people prefer Cryptos.
2. Miners service are decentralize.
Who would ever thought that they could get you a 1$ transaction of a fee which could be more than a thousand dollar's fee? There is something wrong and miners should be held liable into this by only limiting the transaction fee to be deducted not more than the transacted amount. They are abusing due to the fact that their service is in demand especially the bullish trend of bitcoin.
The capacity of Bitcoin is limited. The fee market is essentially a free market and the market forces is what decides the fees. I don't see the miners interfering in the current situation nor do I think that the rise in the fees are caused by the miners instead of the influx in transactions.
3. The abuse may be only happening and will be resolve between both parties. Same thought about in number 1 but this talk about resolution between both parties and not about the lack of authority from the founder. A certain user could mistakenly send high amount in the transaction without checking it and will be requested for a refund. The other party could deny and there us nothing you could do because it was your fault and no one can help you.
Get a trusted escrow. Bitcoin is reversible. On the contrary, if transactions aren't final, there has to be a third party to make decisions and take sides in the event of a dispute. If you want that, get an escrow.
What you've described so far is basically Paypal or any banking system. Bitcoin is designed to counter some of the undesirable characteristics of such systems. If you want those kinds of restrictive rules, then I don't think you should use Bitcoin or any other cryptos.
