The author considers communion only in terms of his tradition, that it is a somber, introspective church ceremony. So the debate for him is who is eligible to partake of the ritual.
This completely misses the teaching of the passage. The early church was actually gathering together to eat a meal, a "commun"-ity practice:
Acts 2:42 They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer.
The Lord’s Supper was a potluck, not a ceremony. It was likely a joyous event, with lots of laughing. But the problem was, certain people were eating all the food and getting drunk while others were left hungry. This dishonored the Body of Christ, that is, the community of believers:
1 Cor. 11:22 ...do you despise the church of God and humiliate those who have nothing?
The self-examination Paul commanded was to consider one's attitude toward the brothers:
1 Cor. 11:29 For anyone who eats and drinks without recognizing the body eats and drinks judgment on himself.
This thought continues into chapter 12:
1 Cor 12:13 For in one Spirit we were all baptized into one body, whether Jews or Greeks, slave or free, and we were all given one Spirit to drink.
One might say that Paul’s discussion about the Lord’s Supper continues all the way to chapter 14, because it is all regarding how the Body ought to conduct itself when it gathers together.
Clearly we are not dealing with a ritual here. Given this, it almost seems nonsensical to discuss categories of participation in a community meal. In fact, to exclude anyone would be ironic, since that's what Paul was correcting.
