If you're buying block hours I interpret that as paying to be an FO for a company. If you're paying to sit there, that means there's an FO position that should be salaried gone.
If he/she means paying for x amount of twin/single engine piston time to build hours then all they're doing is hour building. That's ok, we've all done it to get the experience required for the licence. My thoughts are if you're going to buy some twin time, go some where interesting that'll challenge you in a measured way. This'll do wonders for consolidation and confidence. Drilling holes in the sky looking at your local area isn't as useful in the great scheme of things.
Better still, if you have a CPL, get a job in an interesting area.
