This became a problem later due to governments cracking down on cryptos and some terrible technical choices made transactions expensive just as adoption was ramping. (Pat yourselves on the back, small blockers.)
My first experience with crypto was buying $5 in bitcoin from a friend. If I didn't do it that way I could go on a number of websites and buy crypto without opening an account, via credit card, or via SMS. Today, most of the $5 would be eaten by fees, and buying for cash from an institution requires slow and intrusive KYC.
