Nope. Humans have really long life cycles. Imagine how long an experiment that requires 2 generations of humans will take?

Behavioral problems, etc make reproducibility harder.

When we can overcome those problems, like with cultured cells, most prefer human cell lines.

But the intention is to have a "model" rather than the full thing.

It seems that people are ignoring the fact that we are already experimenting on humans on a fairly large scale: All drugs in most countries are only approved after a scheme involving 3 phases of trials.

Phase 1 trials are to test safety and possibly design input for the next (phase 2) trial. In particular in oncology, there is no expectation that a patient in phase 1 will even potentially benefit from an experimental drug but there will likely be (detrimental) side effects in the high-dose groups at which point we back off.

So let's acknowledge that many of the (more modern) drugs we take are also a result of fairly heroic consent from human patient volunteers without any chance of personal gain.

The "Self-experimentation in medicine" page has a lot of wild stories that I recommend reading: https://en.wikipedia.org/wiki/Self-experimentation_in_medici...

I agree with you and I believe you should volunteer as a test subject for all experiments you can get your hands on!
