It's actually significantly easier and requires less resources to run a Monero node today than Bitcoin
Monero has a smaller blocksize ~0.3 MB vs 4 MB
Monero has a smaller blockchain ~200 GB vs ~600 GB
Unless you expect Monero to suddenly dethrone Bitcoin, there is no reason why it can't gradually scale. With consumer tech advancements (Moore's law) and protocol scalability improvements (tx size already reduced by ~80% since inception) there is no problem.
I affordably fit 1 TB of data on a microSD card the size of a fingernail. That didn't even exist a decade ago.
