sure Hoyle proved that sequential trials are impossible, but that does not make him right or his model accurate. Merely winning a prize for good math doesn't mean your model is realistic.
The only difference between inorganic and organic is their source. And their chemistry of creation is quite important, hence why there are studies of inorganic and organic.
The fundemental problem with the trials that have been done is that they were using small scale models (comparatively) that often didn't have the right mixture of conditions on earth. The Miller-Urey experiment actually got amino acids, but it was using conditions that didn't exist on the planet.
