I would indeed, point is that merchants dont accept crypto directly for payments, but I can use Gift Cards to buy goods and services that I need. It is a longer process, to fund the site where I buy the card and then redeem the card on the merchant site. I would defenitely look forward to directly paying the merchant in crypto in future as acceptance increases.

For Brazil locals, you can use Bitrefill, this is where I get my gift cards from. https://www.bitrefill.com/buy/brazil/?hl=en
