not having node online 24/7 is not necessarily a problem, especially if you buy your channels and do not route (impossible with only private channels anyway). The seller is supposed to keep that channel open during the agreed-upon period, even if you go offline. So the only arguments against this are some inconvenience/extra work and unfamiliarity, and perhaps privacy.
But ok, not throwing any fruit or vegetable, just pointing out there may be better ways, worth of considering at least.
