Dynamic block size is one of the reasons that makes Monero a shitcoin. It makes normies difficult to run a node.
Discussion
Running a monero node isn't more difficult than running a Bitcoin node.
It's because majority people know that Monero is a shitcoin. The more people accept Monero, the harder to run a node.
Larger block sizes have a negative impact on not only storage size but also on verification time.
So your argument is it will be so successful and popular that it will be hard to run a node?
Or do you believe Monero will remain an irrelevant niche?
If the latter then why are you worried about the size growing too large? (not even considering consumer tech is not static and protocol scalability improvements - a strength bitcoin doesn't really have)
What about a coin with high tx fees that will become infeasibly expensive in the future, zero privacy, and lacked real world fungibility.
Expensive, surveillable, and taintable. Sounds difficult for normies to use.
