Pfft. I don't recall any of her heroes being fascists.

Atlas Shrugged was all about individual and corporate personal property rights, and how groups of what today we would call "progressives" shamed individuals who rejected their propaganda using what again, today, we would call "cancel culture".

Ultimately, those "progressives" ended up putting political minders into the employ and on the boards of the noncompliant corporations (precisely what we see today in China) to pressure the individuals into making business decisions approved by the government (so here, the fascists were the government bad guys demanding overregulation) and against the best interests of the corporation, resulting in bankruptcy.

Then further, there was a social demand to abrogate private property rights (in the form of Galt's patents); we've seen similar demands around nationalized banking from the Bernie Sanders types and even more recently, suggestions that the conditions of the pandemic justify the government should they decide to violate Pfizer's and Moderna's patents.

I agree with you as far as to say that Rand does not propose a workable economic system, the negative aspects of her total rejection of altruism, and that her ideas may have (not did, but may have) influenced Greenspan into making errors.

I would suggest to you that a total rejection of Rand as a thinker is just as illogical as those who totally embrace her.
