I spent the whole night organizing this topic just because I didn't want to casually dismiss opinions with a procedural approach.

Writing this, I once again realize why Ethereum and its Layer 2 solutions have a promising future: the key lies in friction. Reducing on-chain interaction friction means lower costs, faster speeds, and a better user experience. This is exactly the core value of L2 architecture.

Whether it's Rollup or Sidechains, these scaling solutions are all working in the same direction—breaking down barriers to adoption. When transaction costs drop from dozens of dollars to a few cents, and confirmation times change from minutes to seconds, the entire ecosystem's imagination is thoroughly unlocked.

This is not just a technological iteration but the beginning of reshaping the market competition landscape.
