This is the paradox of wanting crypto to be both widespread and free of government influence. It cannot gain "market share" without interacting in some form or fashion with the regulatory structures already in place, putting it under de facto regulation of any jurisdiction of the people who want to use it.
Cryptocurrencies like bitcoin are entirely different. Ripple is not like bitcoin and the regulations of the USA and other countries will affect bitcoin’s value but not determine bitcoin’s continuing existence unlike XRP.
