This sort of reply is sad. It’s bad advice.

It’s saying the OP, after asking a fairly-specific question, should be satisfied staying ignorant. That they should be happy not becoming more skilled. It doesn’t really answer the OP’s question at all.

There are many people who ride bikes “casually”, which is fine.

But, with taking the effort of asking the question here, the OP doesn’t seem to want to stay in that group.

I have no idea why anybody would advise them that being a “casual” cyclist is what they should aspire to.

Why not give them useful information and let them choose how to use it?
