It's true that in the early stages of bitcoin there was a benefit of POW which is initial coin/software distribution to create a group of early adopters. After 5 years the bitcoin mining no longer helps bring in new users due to the ASIC cost. But we don't have that early benefit which bitcoin did, of creating thousands of early users via mining, so we do need something to compensate for that.
I was staunchly against inflation to pay for extra marketing at first, but byemaster makes a good point about it being analogous to share dilution/capital infusion. However, with pre-IPO share dilution (as far as I know) there is an investor(s) ready to buy a percentage of the company, so that capital infusion is guaranteed. BTSX is already "ipo'd" so any investors wanting to invest can buy in already. There's no capital infusion with inflation, but rather a capital movement from stakeholders to the marketing team (or wherever the newly created BTSX were allocated, how is that decided btw?).
I can't really know whether to be pro-inflation or not without knowing what the current size of the marketing budget is and what the plans are, but a referral program does sound like it could be worth it if its very well thought out.
