Why would people prefer to use a paypal that settles on the bitcoin network vs a paypal that is based around USD?

I have no idea, but second layer networks have much different properties than a custodial paypal service has.

In terms of USD vs BTC spending - I imagine a lot of people will want to spend USD, and BTC will serve as a store of value and backing asset. USD is possible via stablecoins though.
