Feasibility: What's your plan? blank slate or forced redistribution [of resources]? The latter will require expounding the moral case for overriding an individual's property rights. Face it, people like their possessions. Moreover, how are you going to (1) obtain the necessary information to fully understand how those resources should be distributed [inefficiency beckons], and (2) Process that information [bounded reality is going to hit you like a fucking train]. I don't much like Capitalism either, the inequalities it engenders are reprehensible. However, the individual is always in the best position to know what he or she needs. The feasibility issue is simply that no centralised system [that we've devised so far] of resource distribution can handle the quantity of information in the way that markets can.
This sort of follows from the above. Moreover, the illusion of freedom is something we live with for most of our lives in some form. Example: Metaphysics, determinism and free will. I always find it difficult to convincingly refute determinism, but I'm never willing to let go of the idea of free will. I may accept all manner of philosophical doctrines that lead me to the conclusion that nothing I do I really have control over; yet, when I'm stood in Starbucks deliberating over which beverage I'd like I always feel like I'm free to chose.
I'm quite willing to accept the illusion of choice that I feel day in day out because it's a functional idea. This, to me, can transfer over to political/economic freedom. It's part of the price we pay for a system that creates inequality, but also drives innovation.
Also, note: by most (and a wide set of) measurements those with capitalist systems often rank highly in Happiness/Quality of Life indices. Admittedly, those with regulated, social democratic capitalist systems rank highest, e.g. Scandinavian countries. So, the whole, "your freedom is a lie" thing doesn't seem to be that big of a deal to most people.
Isn't capitalism's core premise private ownership and enterprise? Its core premise is that each person should be in a position to make their own economic decisions. Active agency, etc. There is a consequential asymmetry of ownership [and power] within capitalist systems for xyz reasons. Now, capitalism has serious issues as you outlined: predatory practises, manipulation of markets, exploiting, etc. Nevertheless, ref. (1): the individual agent is still in the best position to understand his/her needs and wants. Despite its flaws capitalism does provide an apparatus by which X individual can act in A, B, C ways to obtain his or her desired ends, i.e. earn munnies, buy goods.
Anyway, the Communist ideal is not the solution. Pragmatic socialist policies that seek reform and regulation of markets are the best approach because they're a compromise between the two extremes.
tbh something like a Communist utopia is probably where we'll end up, but only once we've solved scarcity. When I say "technological innovation will liberate us" I have my eye on the potential of Nuclear Fusion to provide abundant clean energy; genetically modified crops to produce near-abundant food supplies. Look at the potential brown sticky stuffshow that automation of jobs could cause. It is not inconceivable that in 100, 200 years we may arrive at a point at which we can automate every production job - production of food, housing, etc blah blah - and quite literally give everyone whatever they want, thereby removing the need for a market economy to distribute goods [because scarcity is no longer an issue, you just have a huge centralised pile of everything and x person requires a good and gets it instantly].
also, innovation in capitalist markets is unrivalled.
I almost get the feeling that your gripe isn't with capitalism and the markets, but more so the distribution of power in which political elites are able to change things in their favour.
