A homemade pastry has fewer preservatives and additives, you have greater control over the contents, requires a time and effort investment, and is not heavily marketed with prominent placement in grocery stores and appealing, colorful packaging. There are both nutritional and psychological differences between the two that make the homemade version effectively much less unhealthy for you.
False and irrelevant. False, because there's way more than one kind of sugar - glucose, fructose, sucrose, lactose, and more, not to mention cane sugar vs. HFCS. Irrelevant, because there are other non-sugar things in commercial food products that cause you to want to consume the products more, which causes you to consume more sugar. Finally, who says that I put more sugar in my pastries than Hostess does?
I'm not sure if you're missing the point intentionally or unintentionally but while those chemicals sometimes can cause health problems later in life but the sugar is what's causing the calories that are causing the obesity that is causing the health problems we want to mitigate.
The sugar is the problem and both the pastries have the same sugar. The homemade one may be marginally better but it's a distinction without a meaningful difference. The problems caused by oddball chemicals used in industrial food manufacturing are less than a rounding error compared to the problems caused by obesity.
No, it is actually both things. The sugar causes people to eat the stuff and does contribute to obesity, but sugar is only a contributer. The additives and ingredients like vegetable oils (which cause health problems of their own due to their chemical structure) also contain a lot of calories (fat contains more calories per gram than sugar).
In Australia obesity increased while sugar consumption decreased. The additives really matter and have a huge impact on human health--they are not a rounding error, but it was a great marketing tactic on behalf of various food industry groups to vilify sugar while deflecting from the other ingredients that are similarly problematic.

Which are present in home cooked baked goods too.
I know it's not as simple as just "sugar=fat" but the difference between home cooked junk food and industrially cooked junk food is vanishingly small.
What kind of flour has sugar in it? Most flours are a mixture of starches and protein from grinding up a grain. Starches take more work to digest than sugars, so they don't spike blood sugar levels as quickly.
You can choose to put less sugar in your homemade pastries. I sometimes bake cookies at home and I use less than half the "recommended" sugar amount, and they still taste sweet. I've never really liked commercial sweet baked food because the high amount of sugar causes a "burning" sensation when I eat them.
You can also buy sugar free pastries. You can also add extra sugar when you bake your pastries.
I don't understand how this invalidates my point that sugar is sugar. That there is no difference between sugar in commercial goods, and sugar you add when you bake at home.
Sure, I think the parallel you're trying to draw is that you can also buy diet coke instead of regular coke, but many will vehemently argue that it's not the same thing.
I'm sure given enough effort, I _could_ find cookies made with half the sugar and dark chocolate, but if you asked me right now, I honestly couldn't tell you where to find such a thing, let alone at a price comparable to run-off-the-mill chips ahoy (never mind the cost of baking them from scratch).
We can certainly be pedantic and say one molecule of glucose is identical to another, but the logistics of buying cookies on impulse at the supermarket vs taking out a mixer to make them on a saturday morning will realistically not likely yield identical amounts of sugar intake. There's also something to be said about the shock of learning how much butter goes into these things!
You can certainly buy low-sugar/no-sugar commercial goods. You can also bake pastries with extra sugar. Quantity of sugar does matter but sugar is sugar.
