Arguably, you can't destroy corporate personhood without doing a lot of damage to capitalism itself.
One problem that corporate personhood was meant to solve was that owning part of a business becomes a legally risky thing when the business isn't a separate person from its owners. Incorporation creates a legal firewall that, for example, allows me to own stock in Apple without having to fear that I will get personally sued if they do something wrong, or that someone will be able to go after my personal assets if they go bankrupt.
It also makes it easier for me to interact with the corporation in certain ways - for example, if I have a grievance against something Apple did, I can name a single, easy to identify entity in my lawsuit, rather than having to pursue a case against a whole slew of individuals. The latter would be a prohibitively difficult effort, since you'd have to figure out exactly which individual are responsible in order to name them in the lawsuit, and then deal with a whole bunch of additional litigation in order to allocate liability among all the people involved in whatever thing it is you're suing them about.
There is still a question of exactly what rights and responsibilities a corporate person should get. Many legal jurisdictions, including the United States, have historically been very liberal in granting natural rights to corporations, and there's plenty of room to argue that they've gone too far. But I don't think there's much room for arguing against the idea that at least some aspects of corporate personhood actually work out to the benefit of people who interact with corporations.
