Nobody actually needs to fly an aircraft like this and any justification offered for it must sound fatuous.
Still, it's interesting to think that such an aircraft might actually come to exist and enter service.
I would be fun to spot for these at the major airports, with plenty of commercial service, from which this type would inevitably operate.
If I could afford the thing, or get someone else to pay for it, like the shareholders, I'd not mind having one myself.
The technical development that this aircraft would represent is a precursor of things to come, like a future Mach 2+ commercial Pacific-crosser.
