Who will be replicating it? Why would I want to set aside my own research to replicate some claim someone made? How would this help my career?
This could help your career by increasing the probability that the work you're citing is more likely accurate, and as a result, your work is also likely more accurate.
If the cited work is unable to be replicated, and you try to replicate but get different results, then you would be doing original research, and then you can base further work on your initial original study that came to a different result.
On the flip side, if you are able to replicate it, then you are doing extra work initially, but after replicating the work you've cited, the work you've done is more likely to be reproducible by someone else.
The amount of citations needed to require replication could itself be a function of how easy it is to replicate work across an entire field.
A field where there's a high rate of success in replicating work could have a higher threshold for requiring replication compared to a field where it's difficult to replicate work.
Also your mentality is exactly part of the problem: you arrogantly believe that replication work is beneath you and that originality is all that matters.
High-impact work that people care about gets built on, and replicated. Low impact work does not.
My results can be confirmed by anyone who wishes to do so, because I always publish my code.

I’ve done plenty of replication work when it was needed for my research. Replicating other people’s work however is not my responsibility and it is not usually required to perform original research.
so you want to do science.... which requires there to be replication.... but somehow it's not your responsibility to replicate anything? last I checked the scientific method has to be followed through all the steps to be valid, not just the ones that you personally like
1. I don't trust the results
2. I want to understand their work in sufficient detail
Usually these reasons apply when I'm building directly on top of someone's work. This is not always the case. Often my research is based on ideas which could be tested by generating my own results. As long as I can replicate my own results I don't see a problem.
replicating your own results is not science though, it's anectodes
