An individual boycotting animal products has no measurable impact on demand and the relationship between demand and supply is more complex then the idea that reduced demand -> reduced supply.
I already covered this in my reply to you above.

There's also a thread on this issue exploring it in more depth:

And entire papers have been written on the subject. Margaret linked one recently, although I can't find it right now. I'll tag her in and maybe she can link it.
This kind of defeatist argument appealing to immeasurable consequence is in no way rational, and it doesn't map to any reasonable moral system.
As a closely related argument, it's MUCH more reasonable to talk about the psychological effects of green purchasing, in that people have a tendency to offset their good behavior by doing more harm; particularly relevant to more superficial actions like recycling (I've given the example of pet adoption before). Monbiot gives an example of a couple using their vouchers from recycling to fly to the Caribbean here:

Is it a risk that vegans may justify not feeling guilt for other environmentally harmful actions because they're vegan? Yes. We tend to be more critical of that here. On a personal level, I try to do a little better every year, because I don't assume that veganism is the moral baseline.
The counter-argument would be: Are YOU planning to overcompensate for a vegan diet by doing more harm elsewhere? If not, then it's not an argument against going vegan yourself. It just may temper our expectations for consumer change.
To be clear, there's no reason to think vegans would as a group do worse than other consumers, and given correlations with minimalism they probably do a lot better, but it's an argument you could make as a possibility in terms of the limited effect of consumer outreach.
Arguing that we can't measure the precise effects of a single consumer is not an argument against moral responsibility.
You're also completely missing the notion of shared culpability:
Ten people simultaneously shoot a victim. If we assume that the victim would still have died with nine gunshot wounds, then if any one of them didn't shoot it wouldn't make any difference. Then are they each completely innocent, and is nobody in any way to blame for the murder?
This "if only I stop it won't have any effect" mentality is common, and it's a major impediment to social change. It's a bad mentality. If you regard with any credibility models of ethics which examine actions as universifiable rules that would have good outcomes, or participating in accordance with a moral game theory, you have to recognize that you're doing a significant wrong by participating in such systems according to such a rule consequentialism.

I support political and cultural changes
That's great, but what does that mean?
It is within your power to do more. We don't know how or if culture will change (it's much less likely to happen with that defeatist mentality to personal change), but we all have control over our own behavior.
Do you, or have you ever, made any effort at reduction?

There is no contradiction when a person disagrees with a practice but doesn't boycott it. You're importing a hidden premise here, namely, the idea that if someone disagrees with a practice they are some how morally obligated to boycott the practice.
The contradiction becomes apparent with a more robust understanding of statistical consequence; I don't think that requires any imported premises.
However, a practice we disagree with may not be avoided if doing so comes at the cost of doing some other more urgent good. Think aid workers who live in developing countries and have limited access to adequate vegan diets or have to rely on canteens or provided food.
There are legitimate reasons to not be vegan (or whatever comparable reduction heuristic you prefer) because of the costs of doing it in some circumstances, but otherwise there is a moral pressure there.

Yes, researchers are still trying to prefect the taste and texture of clean meat. Start-ups claim they're 3-5 years away from entering the market. Hopefully they have perfected the taste and texture, and learned to grow fat/plant-based fat molecules along with the muscle cells.
Start-ups claim all sorts of things all of which you should be very skeptical about, that is because a start-ups existence hinges on attracting investors and as such there are strong incentives to hype and bullshit.
This is a good point.
