While good points, these counter arguments are not strong enough.
Trustable Experience: Most people make many transactions in a week that are not trustable. The lower the price the lower the hesitation. $0.99 is as low as it gets.
Free alternative: For many transaction higher than $0.99 there are free alternatives. Newspapers, magazines all have free substitutes online. Still people spend on these.
Craftsmanship: True for Starbucks, not for majority of transactions. Maybe be not even... most people are staring at their phone anyway waiting for their coffee.
