Eth is so good because it has the highest level security securing its blockchain. You also didnt mention scaling solutions in which will help along with sharding help scale Ethereums. It is false to say it has reached limit, you can build on top of Ethereum and extend its capacity.

There is a reason why Redditts is choosing to have their community points secured by Ethereum. Its high fees are a result of so many applications and users fighting for its limited blockspace.

Although fees are high now, i expect in 2-3 years once scaling solutions in mature and deliver fees will be extremely low, as users will not be Interacting with Etheruem 1, but will be using other layers for general interaction.

This is why i think ETH is going to 20-50k+in the medium term, because ppl seem to think it will be this way forever and cant look passed the immediate in short term. Because ppl who want the best security will use Ethereum and eventually theyll be able to do it at very very low cost. All while inherenting the security of Etheruem on these l2s.

It isnt zero sum, and i see other blockchains beinjg widely used due to the huge amounts in of demand for blockspace, but if Ethereum delivers and l2s all come together then the main negative and think probably keep price down and stopping growth are fixed and i see Ethereum really coming into its own esp over a 2-5 timeframe.
