That.. still requires funding. Even if your lab happens to have all the equipment required to replicate you're paying the grad student for their time spent on replicating this paper and you'll need to buy some supplies; chemicals, animal subjects, pay for shared equipment time, etc.

Grad students don’t get to publish a thesis on reproduction. Everyone from the undergraduate research assistant to the tenured professor with research chairs are hyper focused on “publishing” as much “positive result” on “novel” work as possible

You may well know this, but I get the sense that it isn’t necessarily common knowledge, so I want to spell it out anyway:

In a lot of cases, the salary for a grad student or tech is small potatoes next to the cost of the consumables they use in their work.

For example,I work for a lab that does a lot of sequencing, and if we’re busy one tech can use 10k worth of reagents in a week.

Grad students have this weird habit of eating food and renting places to live, though, so that's also money

Enough people will falsify the replication and pocket the money, taking you back to where you were in the first place and poorer for it. The loss of trust is an existential problem for the USA.

Yeah, but doesn't publishing an easily falsifiable paper end one?
