Potential losses on naked short calls are unlimited, so as you no doubt know, swimming entirely naked is in principle a dangerous game.
This is particularly especially true in some markets such as in individual stocks, where there exists the very real (black-swan fat tail) risk of a buy-out or some other bullish event causing substantial or ruinous losses.
Moreover call side premium tends to present slim pickings by and large, so you have to be really selective for the absolute best opportunities and not be tempted into taking on risk without collecting sufficient reward when evaluating call side opportunities. Getting in on less than desirable call side trades is a tempting mistake to make, premium and risk being usually but not always skewed to and richer on the downside (put side).
What this means in practice is that as for me, I almost always much prefer to put a "synthetic naked" trades on rather than an actual naked trade, and for the above reasons this is doubly true of short calls. This is to say, instead of putting an actual naked short option trade on, you put on a wide spread instead (e.g. "synthetic naked"), thus defining/capping/winging-off the risk, yet the spread retaining most of the behaviour and dynamics of the naked option due to being sufficiently wide, collecting almost as much premium as you would have done had the trade been entirely naked.
Additionally, there are of course markets other than single stock underlyings which are intrinsically more neutral and mean-reverting or in any case not subject to such stock extreme-dislocation related risks (e.g. such as buyouts), which might be better suited to near-naked call-side premium trades, such as some currency and currency futures options (but again, beware), or perhaps, broad market ETFs.
Remember that with every trade you put on, real risk is risk taken on. There is no reward without risk, there is no free lunch. You'd better have a good idea what your exposure/worst case is, both in terms of individual positions and overall.
The market is just waiting to find out how it can punch you in the face and make you hurt when you least expect it. Being engaged in the market actively and constantly increases the likelihood over time to a near dead certainty that you'll be exposed to some unexpected and unpleasant market event or events at some point. So, at some point you will get punched in the face, and when (not if, when) that happens you must be able to survive; grimace, wince, brush yourself off and then move on and/or bear the adversity for a while. You cannot do that if you've been KO'd or killed.
