Using a 11 year old laptop isn't the reason you're able to spend $30k+ on travel over an 18 month period. Including that is like when people say "stop buying Starbucks if you want to buy a house." There are typically other circumstances are involved, even a $8 coffee every day is only $3,000 a year. That isn't make or break for getting a mortgage.
I agree with your point, but Tlto be fair, they also mentioned they don't own a car, which can prevent them from traveling depending on the condition and type of car they choose.
