Are capital gains ultimate crypto hurdle?

Hey, I’m bullish on crypto/bitcoin, but I can’t help but feel so long as every token transaction is liable for capital gains tax it will never reach wide adoption as currency. Of course regular currency transactions have taxes too (sales tax, etc), but for most purchases these r much lower percentages.

Am I right in thinking the most important battlefield for widespread adoption of crypto/bitcoin is how they’re taxed? (Not discounting infrastructure/community as supremely important).

If not, what would be the optimistic counter to this?

(Where r the debate questions asking presidential candidates who they’ll nominate for SEC chair!)
